WineEast Should similar insecticide longev- ity be found in hot climates, the reduction in insecticide use from the above strategy could result in both economic and environ- mental benefits. and excellent coverage can provide effective control to grape clusters for more than two months.2 Sticky traps are baited with pheromones from the female grape berry moth. well-timed insecticide is applied thoroughly in the fruit zone for the first generation, season-long control could be achieved in hot seasons. Research by Michigan State University has demonstrated that a single applica- tion of methoxyfenozide (Intrepid 2F, Dow Agro-Sciences) applied with a surfactant GreenHoe_NewAd_1/4_9/22.qxp 9/28/09 9:30 AM Page 1 An insecticide timing trial was conducted in the five commercial vineyards in the Texas Gulf Coast region during the 2009 season to determine the best time to apply methoxyfenozide for season-long control of GBM. The results showed that season-long berry infestation was reduced the most by applying methoxyfenozide within 7 days of the first male moth capture in pheromone traps along the vineyard edge. Waiting as long as 14 days resulted in about a 50% reduction in season-long infestations compared to later or untreated clusters, although the earlier application was signifi- cantly better. We noted in the three-year trapping study between 2007 and 2009 that Blanc Du Bois clusters had approximate- ly BB-size berries when the first moth GREEN GRAPE HOE Specialized Tools For Vineyards Weed Control and In-Row cultivation Basic Hoe comes with a Hillup and a Takeaway Blade.
