At the same time, domestic phoxim was used as a reference medicament. First, the test method 10% of cypermethrin EC (British Bu Neimeng company) set acres spray 50 grams, 150 grams and blank control three treatment; 20% of the speed off killing Ding EC (produced by Sumitomo Chemical Industry Co., Ltd.) Mu spray 20 40 grams and blank control three treatments; 50% phoxim (Tianjin Pesticide Factory) set acres spray 40 grams, 60 grams, 80 grams and blank control four treatment. Each treatment area of 50 acres, a total area of 500 acres of test, each working spray liquid 5 kg, the aircraft flight height of 5-7 meters.
