Apple, Codling Moth Control with Neemix, Dipel 2X, Imidan and Guthion, 1995

Neemix, alone and in combination with Dipel 2X, Imidan and Guthion were evaluated for their ability to control CM over the entire season. The test was conducted in an apple orchard at the Tree Fruit Research and Extension Center. The trees were 15-yr-old spur type Delicious on dwarfing roots. Treatments were applied to 1-tree plots replicated 5 times in a RCB design. All treatments were applied with a handgun sprayer at 300 psi to the point of drip. The CM injury evaluations were made following the first generation on 19 Jun and at harvest on 31 Aug. Twenty-five apples per replicate were sampled on 19 Jun and the number of fruit injured by CM recorded. At harvest, all the fruits per replicate were sampled and the number of CM and PLR injured fruit recorded. Due to the high percentage of CM-injured fruit at harvest, a 10-fruit subsample was chosen at random from each replicate and the number of CM stings and entries per fruit recorded.
