Northeast Volume 1, Issue 1 VEGETABLE PEST MANAGEMENT Innovative Solutions to Protect Fruits and Vegetables Beat the Bugs to the Box Northeast vegetable growers have but one goal: fill as many boxes as possible from every acre. The challenge is to beat the bugs to the box. Following a warm winter, that challenge may be greater this season. It could be a worse year for insect pressure, says Dr. Brian Nault, entomologist from Cornell University. If temperatures continue to be moderate or above average, some insects could have an extra generation. Nault suspects thrips, aphids and corn earworm could be bigger issues this season. Mike Manak Chris Pawelski Mike Manak, a consultant for Crop Protection Services, is encouraging growers in western New York to start scouting earlier and to watch for disease. He suspects disease pressure will be heavier in fields flooded in 211. The only way that forecast changes onion grower Chris Pawelski s management plan is he ll be ready to treat sooner. Like any grower, he pushes for high quality and yield. His per-acre yield goal is 8 5-pound bags of medium-size onions. To meet that goal, he can t skimp on management. Penny wise, pound foolish, Pawelski says. When you start short-changing on rates and surfactants, you re hurting yourself. I don t skimp on anything. Pawelski uses a systemic fungicide throughout the season. For insects, he starts with an early season material that s focused on nymphs and has a longer postharvest interval, then moves to Radiant SC insecticide (see Chart 1). He applies Radiant at 8 to 9 oz./a with a pint of surfactant and averages six sprays each season. Radiant is bang-up, Pawelski says. Manak recommends Radiant for two reasons: It s the most effective product for controlling nymph and adult thrips, armyworms and leafminers, and it has a short preharvest (Continued on Page 2) Why Use Radiant SC Insecticide? Target Three Bugs. Thrips, worms and leafminers with one jug. Resistance Management. Radiant SC insecticide, a Group 5 insecticide, offers a unique mode of action essential for resistance management. Partner it with Intrepid 2F insecticide, a Group 18 insecticide, for efficacious worm management. Prime for Export. Maximum residue levels (MRLs) are established for many countries, including Japan, Taiwan, Canada and Europe. Ease of Management. Radiant offers a four-hour re-entry interval (REI) and a one-day preharvest interval (PHI) for most vegetable crops. Integrated Pest Management (IPM). Radiant preserves beneficials. Environmental Stewardship. Radiant was accepted for registration under the Reduced Risk Pesticide Initiative of the U.S. Environmental Protection Agency. The active ingredient found in Radiant, spinetoram, received the 28 Presidential Green Chemistry Challenge Award. (Continued on Page 2)
(continued from Page 1) interval. He recommends back-to-back shots at a 6 oz./a rate with a nonionic surfactant mixed at.25 to.5 percent applied on a seven- to 1-day interval. Andy Fordice, product manager for Dow AgroSciences, notes Radiant is ideally suited for a year likely to be marked by heavy insect pressure. In addition to targeting yield-robbing pests, it also holds a grower s pest management partner beneficial insects close to the field. There isn t anything else out there that gets the spectrum of pests that Radiant does and is still good for beneficials, Fordice says. CONTROL OF ONION THRIPS DR.

Gets pests that are outside of the direct line of spray. Label Expanded on Dithane F-45 Rainshield Fungicide Vegetable growers already know Dithane F-45 Rainshield fungicide offers broad-spectrum disease control on dozens of crops with little risk of developing resistance. The only thing Dithane F-45 lacked last season was a label for lettuce and peppers. Consider that problem solved. In March, the U.S. Environmental Protection Agency (EPA) accepted an expanded label on this essential fungicide to include downy mildew in lettuce and anthracnose, early blight and phomopsis blight in peppers. Growers can treat with a ground application, aerially or through chemigation. The keys are to scout closely, begin application when the disease appears and ensure thorough coverage with each treatment, reapplying on a seven- to 1-day schedule. Dithane F-45, with the active ingredient mancozeb, is a multisite inhibitor that stops fungi at various points during development. Because of this, no resistance issues have arisen in any crop for any disease. Not only does Dithane F-45 offer minimal risk of resistance, it also carries a high margin of crop safety, with low persistence in the environment and no leaching potential. With Rainshield technology, a unique combination of surfactants and wetting agents built into the liquid flowable formulation, Dithane F-45 offers exceptional rainfastness, redistribution qualities and plant adhesion. Applications not only stick to plants but also redistribute on plant surfaces. Dithane F-45 Rainshield fungicide features ultra-small particles that rapidly disperse in the spray solution. It is easy to pour, with virtually no dust, and is nonabrasive to equipment.
Go Bold With Intrepid 2F Insecticide It s not only the early bird that gets the worm; it s also the management-savvy vegetable grower. Figure 1 Product Options and (Insecticide Classes) Rotate between circles (not within) Worms that enjoyed a snug hibernation during the warm winter in the Northeast are likely to start out hungry early in the season. Growers who meet them in the field with Intrepid 2F insecticide can stop them in their tracks and leave open the opportunity to rotate into other products later in the season. Intrepid 2F, a Group 18 insecticide, contains a unique mode of action that makes it an ideal rotation partner for effective resistance management. Other insecticides often share modes of action (see Figure 1). Using Intrepid 2F adds strength to resistance management while gently treating the environment and beneficial insects, making it an excellent option for both Integrated Pest Management (IPM) and resistance management. Actara Admire Assail Provado Venom (4A) Lorsban Advanced (1B) Radiant SC (5) Intrepid 2F demonstrates no toxicological effects to most beneficial insects, mites and pollinators, including bees. This makes Intrepid 2F insecticide an ideal choice for effective control of foliage-feeding worms of all sizes. Visit www.intrepid2f.com for more information.

Control Powdery Mildew on All Leaf Surfaces Powdery mildew doesn t choose sides. It attacks leaf surfaces from all angles, which is what has made Quintec fungicide such a valuable part of a spray program for powdery mildew. Quintec, which is the industry standard for powdery mildew control in crops such as pumpkins, lettuce, melons and strawberries, is highly efficacious against powdery mildew because of its ability to redistribute around the crop and its foliage. This redistribution allows Quintec to provide coverage of both upper and lower leaf surfaces (see Chart 2). Powdery Mildew Percent Incidence POWDERY MILDEW CONTROL IN CUCURBITS DR.

Rally 4WSP Chart 2 Upper Leaf Surface Lower Leaf Surface Microthiol Disperss Bacterial spot is another disease that s caused pepper producers issues over the years. Quintec aids in the management of bacterial spot both when rotated with Kocide and a mancozeb fungicide, such as Dithane F-45 Rainshield fungicide, the current standard treatment of Agri-Mycin (see Chart 3). Similar to insecticides, resistance management is a key component in sustaining product efficacy for fungicides. Quintec, a Group 3 fungicide, is the only member of the quinoline class of chemistry. The unique mode of action found in Quintec fungicide makes it an ideal rotation partner with Rally 4WSP fungicide for effective powdery mildew control in a resistance management program. Visit www.quintecfungicide.com for more information. Double the Control With Rally 4WSP Fungicide Dow AgroSciences offers not one, but two trusted products for the control of powdery mildew. Rally 4WSP fungicide teams with Quintec fungicide to provide vegetable growers with a pair of effective options when battling powdery mildew. Rally 4WSP, a sterol inhibitor, is an ideal rotation partner with Quintec in a powdery mildew program. Rally 4WSP has proven to be a consistently effective option for powdery mildew control during both low- and high-pressure situations. It is registered for control of diseases in multiple vegetable crops, such as tomatoes, peppers, snap beans, cucurbits and strawberries. The systemic activity of Rally 4WSP resists wash-off, increases residual activity and protects new growth. While Rally 4WSP offers systemic and curative activity, it should be used primarily as a protectant fungicide.
