INSTRUCTIONS FOR USE
NoMate PBW Fiber is intended for use in controlling pink bollworm damage in cotton by preventing male moths from finding and mating with females. Its use results in reduced crop damage by suppression of fertile egg laying and larval infestation.
TIME OF APPLICATION
1. Monitoring to detect the time of peak emergence should begin when fields are planted using Scentry \"Delta\" traps baited with Scentry lures. During the season, monitoring should continue on a frequent basis (every 1-3 days is suggested) to help you schedule NoMate PBW application for most effective control.
2. The first application should be made prior to the time when the number of adult moths present is large enough to produce a damaging larval infestation.
A. In many areas, particularly those with a history of larval infestations early in the season, start applications shortly before plants produce the first set of buds (squares).
B. If overwintering survival of pink bollworms is low, as indicated by field monitoring and history of infestation, start applications at or just prior to first blooms .
3. Second and subsequent applications should be made before effect of the previous application significantly diminishes. Do not allow periods between applications of NoMate PBW when mating suppression is no longer effective. Reapply based on the following factors or combinations of them.
A. When traps begin to catch moths again, some male moths may be able to find females and another application may be needed. Zero or low trap catches are an indication that the last application of NoMate PBW is working.
B. NoMate PBW is designed to last up to 14 days at temperatures of 100°-1050F. Lower temperatures may extend longevity, higher temperatures can reduce longevity. During low temperature conditions, the time between applications should not exceed 21 days.
C. Pink bollworm infestations in a field will vary from time to time, usually in cycles from comparatively low to high. When trap catches (and other indicators) show that the population is approaching a high level (peak), it is especially important to be sure that the last application of NoMate PBW is still effective, or to make another application.
D. Severe weather conditions such as heavy wind and rain can cause \"fibers\" to be knocked off the plants and thus reduce the longevity of a treatment. Fields should be checked soon after such weather to determine if another application is needed.
METHODS OF FlELD APPLICATION
Applications of NoMate PBW by air require specially designed equipment which is available from Scentry, a Division of Ecogen Inc. Local custom applicators have this equipment and are prepared to provide application services.
1. With air application equipment, applications can be made by flying with rows or across rows and fiber distribution should be as even as possible. A flying altitude of 15-50 feet is recommended with higher altitudes being flown when ground winds are still or moderate and lower altitudes flown as necessary to compensate for high ground wind conditions.
2. Scentry Bio-Tac adhesive, an inert sticker, is available from your NoMate PBW supplier and is used to hold individual fibers on cotton foliage. For best results, before mixing with Bio-Tac, keep bags of NoMate PBW sealed and in a cool place (72°F [22°C] or below). See Bio-Tac label for instructions about mixing ratios and other important information. If an insecticide is used, it should be added to Bio-Tac, then add NoMate PBW fibers to the mixture. Mix only the amount to be used immediately. The mixture should be applied according to application machinery requirements.
3. Storing partially used bags of NoMate PBW is NOT RECOMMENDED. NoMate PBW is available in both 600 gram and 150 grams bags. When preparing for an application, a combination of these sizes containing the amount needed for the application (or slightly more) should be used.
4. Applications can be made at any time of day.
5. Application should only be made by a qualified person to insure proper rate and method of application.
NOTE: Limiting the use of conventional insecticides may help to maintain the population of predators and parasites to assist in the biological control of other pests in the field.
