For peach aphids, the difficulty of removing them for many years has been significantly lower than that of peach borer and apple leaf roller moth. However, the special situation last year has risen to a pest that is more difficult to control in peach production. High, in addition to the difficulty of governance, is indeed a rare phenomenon in recent years. Take Changhaiwen, a fruit farmer in Daxiejie Village, Shakouji Township, Wei County, Handan City as an example. In 2014, the amount of pesticides used in the treatment of peach aphid (calculated as 10% of Imidacloprid WP for conventional products) has been 3000 times that of recent years. It has soared to 375 times, and although the amount of medication has increased by 8 times, it is still unresolved. There was no way to add 30% acetomethionin EC 1000 times. Although the control was a little better, some phytotoxicity appeared on the leaves. He scratched his head and he did not know that he should be treated with peony. it is good. Later, with the help of relevant scientific and technical personnel, the "Red medlar" brand 40% acetamiprid soluble powder 1500 times was used, although it was also 4-5 times the amount of conventional dosage, but it was 95%. The effect of the treatment is that the peach aphid is basically clean and clean, and the effective period of the efficacy is more than 30 days, and no phytotoxicity has yet occurred. He was so happy that he was happy to see the effect of prevention and treatment. Later, he also taught this method to his neighbors and was well received by everyone. The locusts that injure peach trees include peach aphid, peach acacia, peach aphid, and spiraea. Widespread, widespread harm. In general, adults and nymphs cluster on buds, leaves and young shoots to suck and sap, resulting in irregular curling and shrinking of the victim's leaf margins. The damaged leaves are uneven, turning pale green and turning pink, when severe The entire leaf curls like a rope, eventually causing the leaves to dry or fall off. Peach mealybugs and Spiraea indica also accumulated white wax powder inside the leaves, causing the leaves to fall early and the shoots to dry. It also excretes honeydew, which induces mildew. Judging from the occurrence regularity of several aphids, peach aphid occurs in our land for 20-30 generations a year, peach aphid produces 10-20 generations a year, and other aphids are more than 10 generations. All eggs were overwintered in buds and bark gaps of peach trees. The damage parts were leaves, and the occurrence of damage was basically the same. In May and October, it was the peak period of two damages. The control period was basically the same. In view of the occurrence of Peach tree borers last year, coupled with winter and warm winter, it is expected that the damage this year will not be worse than last year. For this reason, it is recommended that the following points should be made in the prevention and control: 1. Spray 10% imidacloprid wettable powder 1500-2000 times before flowering, or 70% imidacloprid water dispersible granules 2500-3000 times + 4.5% high efficiency cypermethrin EC, 50% malathion EC each 1200 times ( Or add 10.7% poisonous insect king emulsion 1000 times) to kill the overwintering eggs. 2. After the fall of flowers, the duration of the damage continued until after spraying 10.7% of the poisonous insect king 1000 times solution + 2% of a Dimensional cream 1500 times liquid, 50% Thiamethoxam water dispersible granules 2500-3000 times solution. 3. During the flood season, use 10.7% of poisonous insect king emulsion oil 1000 times solution +2% methyl-dimensional salt emulsifiable concentrate 1500 times solution and "Red Scorpion" brand 40% acetamiprid soluble powder 1500-2000 times solution for prevention and cure.
