Announcements
Greenhouse IPM - Thursday, May 1st at Jim Girards greenhouse in Kingsbury from 12-4 pm. Dr. Jana Lamboy, the NYS Greenhouse IPM Specialist will lead participants in a hands-on scouting workshop. The use of biological controls will be taught. Call 1-800-548-0881 to reserve a spot.

Money on the Stump - Saturday, May 10th at the South Glens Falls High School. 9 am to 4 pm. Learn about how to maximize the profit from your woodlot. Timber harvests can be extremely profitable if well managed - don't make the same mistake that lots of property owners do. A Forest management plan will turn woodlots into an investment rather than a non-paying liability.

Farmers Markets Looking For Vendors
The Washington County Farmers Markets are looking for vendors of locally produced fruits, vegetables, ornamental plants and flowers, jellies, juices, fiber products, eggs, meats, maple and any other farm product. For more information on dates and market rules, call Bob Andersen 854-3750 or Lillian Valyer 792-7214. Currently there are 5 markets in Washington County with the hopes of having two additional markets in Greenwich and Cambridge. For the Greenwich market, contact Bob Andersen, for the Cambridge market, contact the Cambridge Valley Chamber of Commerce at 677-0887.

DAIRY NOTES: It has been a LONG and COLD winter! The only good thing about this winter is that it wipes the slate clean of last years cropping and harvesting seasons. We now get a chance to make a fresh start at planting and harvesting once again. Planning ahead of time for high quality forages will only benefit you down the road. The quality of alfalfa affects the cost of grain incorporated into the cow's diet. Studies have shown that the price of grain can increase as much as $.14/cow/day for alfalfa harvested 14 days past the ideal time to harvest and as much as $.38/cow/day for waiting 21 days past the ideal time to harvest.
So, how do you determine when to harvest your first cut hay? Some base it on the date of the calendar, such as the last week of May. Others, on one-tenth bloom and yet others on when their neighbors start! Every year is different when it comes to determining the optimum quality of hay. Research was conducted in fields in Eastern NY to determine when the hay was of optimum quality (based on the physiology of the plant). In 1997 optimum quality was June 10th, 1998 - May 6th, 1999 - May 28th, 2000 - May 31st, and 2001 - May 28th.
Growing degree-days (GDD) can be used as a means of projecting maturity in alfalfa in the same way they are used for predicting maturity of corn. GDD is the average of high and low temperature for a particular day subtracted from 41°F. This calculation should begin as soon as the alfalfa comes out of dormancy. The NYS average GDD for alfalfa is 700. At 700 GDD, alfalfa will be approximately 40% NDF. For the best quality alfalfa, harvest should begin at 680 GDD. Give some thought to harvesting your first cut hay now because it could be the most profitable management decision that you make all year long. (Research referenced from Profit Manager, Feb.'03).

FARM BUSINESS NOTES: The current state of the economy is not giving anyone a warm and fuzzy feeling. During the Dairy Farm Business Summary Wrap-up Meeting Tom Kilcer, CCE-Rens. Cty., gave some interesting pointers on costs which are out of line for many farms. Crop costs are one area where most people don't know exactly what they should be when they are comparing notes with their neighbors. Crops are a huge item with tremendous impact - and most people want to err on the side of caution. But when soil tests, crop rotation and understanding your soil resources means that a farm could save some money I think that everyone needs to pay attention. For more info, give us a call or wait for later editions. But start thinking.

LIVESTOCK PEST MANAGEMENT: What will you do this year to control face flies and horn flies in pastured cattle? Do not use the same insecticides all year long - resistant pest populations will develop. Read the labels for animal sprays and dust applicators to be sure they are effective for both face flies and horn flies. Feed additives are usually more effective against horn flies than face flies. Feed additives should also be used on a regional basis, since they kill the maggots in manure and not the adults that already exist. Adults can fly from farm to farm. Ear tags and boluses slowly release the active ingredient and less is released as time goes on. So, it is best to use ear tags and boluses in the summer during peak fly activity, rather than early in the spring.

MANURE MANAGEMENT: What if you do not want to spread some manure this spring. One way to stockpile it without causing an environmental mess, is to mix it with bedded pack and form it into a windrow about 12 ft wide and 5 ft high. Use a box spreader or side delivery spreader so that the flails break up the clumps. A mixture of about 2 - 3 volumes of bedded pack to one volume of wet manure will probably give the right mix so that no liquids ooze from the bottom of your windrows. Mix some up, take a handful and squeeze firmly. No liquid should dribble out of your hand. Then let the windrows compost for a couple of months. When you are ready to spread it, the clumpy bedded pack will be decomposed and spread nicely over hay fields.

Food Safety: Cornell researchers have found that the suggested guideline of 60 days between spreading manure on fruits and vegetable crops and harvest is probably inadequate. They found pathogens surviving in manure-amended soil after 100 days and more. So, be wise and conservative in using raw manure for fruit and vegetable crops.

CROPS
Soil Quality: Now is a good time to inspect tile drainage outlets. Are your tile lines still running? Are newly installed lines working? Is the water coming out clear, or is it dirty (indicating a problem). Look to see where water is laying in the fields. Is tillage to improve the soil structure or subsurface drain the appropriate way to improve these areas?

Beneficial Insects: You may not see many beneficial insects flying around at this time, but ground beetles are becoming active. They are usually black or dark colored and up to an inch long. They eat soft-bodied insects in the soil, like white grubs, wire worm, seed corn maggots, cabbage maggots, and more.

Cover Crops: There has been some snow mold on grasses and winter wheat. I have not noticed any on winter rye. The snow cover may have protected some things like annual ryegrass from being completely killed by the winter, and benefited the sensitive winter annuals like hairy vetch. Check cover crops to see if they did or did not make it through the winter as planned.

Alfalfa: So far I have seen no winter heaving of alfalfa. It seems that snow mold mostly affects the grasses. However, a blanket of snow now with warm temperatures afterward could do some harm. Seed alfalfa and forages as soon as you can prepare the soil without mashing and compacting it. I was asked the proper ratio of grass and alfalfa for horses. Ask your customers and give the customer what they want. The 2003 Cornell Guide for Integrated Field Crop Management has seeding rates and variety trial results for forages. Potato leaf hopper resistant varieties are high yielding and make good sense because there are few if any decent insecticide products for PLH on mixed stands of alfalfa/grass. If you do not scout your fields (shame on you) then PLH resistant varieties are reasonable insurance. Cornell recommends 12 lbs - 15lbs of alfalfa seed per acre. This is less than what other folks recommend. The lower rates work well if your planting conditions are good and weeds are under control. Raptor is now registered in NY as a postemergent herbicide in newly seeded and established alfalfa - for some annual grass and broadleaf weeds. Save money and time by using only secondary tillage to prepare seedbeds on fields with good soil structure - there may be no need to plow fields for new seedings.

Field Corn: Corn is a costly high input crop. So, rotate out of poor and even decent hay fields into corn. Do not use phosphorus (P) in the starter fertilizer if the soil test high in P. The last 3 years of Cornell research have proven this. Do use 30 lbs of nitrogen in the starter fertilizer. I know you do not want to hear this, but you should side-dress any remaining nitrogen rather than putting it on at planting. You are losing at least some and at times most (like last year) of the nitrogen this way. Side-dressing will use the fertilizer more efficiently and provide an opportunity to cultivate weeds that escaped the herbicides. Be sure to plant corn no less than 1 ½ inches deep. See the March/April "Ag Digest" for cost comparisons of various herbicide programs. Plant silage at a rate of 36,500 seed/acre on the most productive soils, down to 30,000 seeds/acre on poor soils. Will your crops be custom harvested? Then talk to your harvester before planting to plan a schedule and select the appropriate hybrid variety.

Grasses: Money is short, but nitrogen (N) fertilizer on grasses gives a good return. Apply up to 100 lbs N as the grasses green up, but do not rut your fields. However, for 2-cut (harvests) of orchardgrass and timothy (bunch grasses), apply only 50 lbs N per acre. Too much nitrogen on grasses cut only twice per year, results in a stand of large grass clumps with lots of bare space between the clumps. This is because the excessive growth and few cuttings reduces the light that reaches the crowns. As a result, fewer tillers (grass side shoots) form and you get thin grass fields. Use high nitrogen rates only on fields cut 3 or more times per year. Potassium (K) and P fertilizers can be applied in late spring if soil tests are not on the low side. There has been snow mold on some grasses. This results when there is a snow cover and warm temperatures. Mold just rots the new and old growth under the snow.

Pasture: Apply nitrogen fertilizer only if you can effectively harvest the rapid spring growth. P and K can be applied in late May to June. K is more available when soils are moist (spring & fall). Plants will take up any excess K without any accompanying yield increase (called luxury consumption). Begin grazing when the grasses have reached 4 inches tall and rotate the animals frequently from paddock to paddock to keep up with the growth.

The new 2003 Cornell Vegetable Recommends is now available from your local Cooperative Extension office. If you want to check it out via the web, the address is http://www.nysaes.cornell.edu/recommends/ . The web version is updated continuously with many links to other web sites with useful information on growing vegetables. Also don't forget the Vegetable MD Online by the Plant Pathology Department at Cornell. It has great pictures. You can go through a selected crop and learn about any disease that might affect that crop. http://VegetableMDOnline.ppath.cornell.edu/Home.htm (from The Vegetable IPM News)

Cucurbits: SUMMARY OF CUCUMBER BEETLE CONTROL STUDY from Umass Extension. A 2-year study comparing effectiveness of insecticides on management of striped cucumber beetles and bacterial wilt in direct seeded (DS) and transplanted (TP) pumpkin (variety Merlin) indicated the need for long distance crop rotation in order for insecticides to be most effective. When rotation was to an adjacent field-different land, but close to last year's cucurbits-beetle numbers were not reduced and insecticide effectiveness tended to decline.

The conventional foliar material carbaryl (Sevin XLR Plus) provided protection to DS plants in 2001 but not to TP in 2001 or either TP or DS in 2002. This may be related to timing: in both years, there was a 2 to 3 day delay between beetle arrival and the first spray, which allowed some feeding to occur. Growers who have used this method are aware that timing is important and because beetle numbers (and leaf damage) increase rapidly in mid-June.

Kaolin clay (Surround WP) provided significant reduction in feeding damage, less loss to wilt, and higher yield in 2001 - but not in 2002. This product is recommended for organic farmers in combination with other tactics such as rotation, row cover, using transplants (so plants are bigger when beetles arrive), and delaying planting until late June to avoid beetles. Surround can be applied to transplants prior to setting in the field.

Imidicloprid (Admire 2F) was effective applied as furrow drench at 1oz/1000 ft in both years. Given the variable row spacing used in cucurbits, calculating rates in terms of ounces per row 1000 feet gives consistent rates at the root zone, and reduces per acre cost at wide row spacings. Admire was also effective through trickle when the full row was saturated with water, even under high beetle pressure. This can be accomplished by charging the system with water first, then making the injection, then running more water to clear the system and ensure wetting of the entire row. A pre-transplant drench provided suppression and reduced wilt but was not as effective as other methods of application. It is possible that slightly higher rates would be more effective, but growers should use caution because excessive rates cause burning.

Solanaceae: Handling Potato Seed by Bill Lamont, Penn State. When it is time to cut seed, warm it up to 55-600 F before handling it (a few degrees per day to prevent condensation on the tuber surface). This minimizes bruising of the seed tubers, which can lead to increased seed rot and stand establishment problems. Quaternary ammonium compounds, sodium hypochlorite (household bleach) and calcium hypochlorite are all effective disinfectants for cutting equpiment. Don't mix seed lots during the cutting and planting process, not only to minimize disease losses, but also to allow you to obtain compensation if there is a problem with a lot. Seed planted into warm, well-drained soil will emerge faster while planting shallow and lightly cultivating to break up compacted soil will also increase the temperature and improve the oxygen levels around the seed piece, decreasing seed decay.

Ornamentals
Landscape: Winter injury is the big challenge this spring. Desiccation injury on all types of evergreens is rampant. Desiccation is a problem when leaves and needles lose water through transpiration, which can happen even when temperatures are below freezing if the sun is shining. This was often the case this winter. Winter winds further complicate the problem. Roots are unable to replenish the water supply because the ground is frozen, so the plants dry up. Landscape managers and homeowners should wait and see how well the plants come out of this before pruning. If the tissue is dead you should prune into healthy tissue after the weather dries out.

White pines are looking really bad. Those trees planted anywhere near roads have a tremendous amount of salt burn from road salt. White pines are not salt tolerant and should not be planted anywhere near roads!!! White pines also look terrible due to breakage from heavy snow loads. Try to prune out ripped and broken limbs.
Bark damage from voles and rabbits is being seen throughout the county. If trees are completely girdled, they will probably bud out and then collapse sometime in late May or June. If clients have specimen trees that they would like to save, you can try bridge grafting, but you should try it ASAP. Vole guards a minimum of 3' in height are the cheapest way to solve this problem.

If you are still facing dormant oil applications, you should try to get it done soon, but be aware that the temperatures fluctuate drastically at this time of year. If there is a danger of freezing within 24 - 48 hours of a dormant oil application you could have plant burn.
As far as disease problems, Rhabdocline needlecast is now visible on last years growth as purplish-brown bands on the upper and lower surfaces of infected needles. Douglas fir is especially susceptible to this disease.

Greenhouse: This winter was devastating to many area greenhouses. The snow load and extreme cold caused houses to collapse, plastic to shatter and in general proved to be a real headache to manage. The spike in heating costs have only added to peoples aggravation. Happily, it seems as though spring is finally here without any major flooding problems.
Cool cloudy conditions in March resulted in problems with Pythium (damping off) for some growers. This disease is not just a problem for seedlings, but causes black root rot on larger plants as well. When temperatures increase and the plant needs more water, the roots are unable to deliver, which causes wilting. These stressed plants then are attacked by Botrytis which finishes them off. Cool root zone temperatures and a high pH favors black root rot. I have visited several greenhouses this spring which are stuggling with water pH that is too high. The optimal range for bedding plant irrigation water is 5.8 - 6.0.

Sluggish growth results when you have cool temperatures and low light. Pushing fertilizer under these conditions will not do any good. These conditions also favor oedema on ivy geraniums. This condition looks like wet bumps primarily on the lower leaf surface.
Cyclamen mites could be a problem on cyclamens. Check the bud area for distortion, bronzed and brittle leaves. Open flowers may have brown, botrytis-like areas on them. Check your Pest Recommends for the miticide options.
