1. Control methods: The use of highly toxic pesticides should not be used during the prevention and treatment to protect the citrifolia weevil, P. gracilis, beetle, beetle, grasshopper, calyx, etc. Natural enemies. Yellow traps can be placed in the greenhouse or in the field to kill adult worms (paint the plate orange-yellow, and then apply a layer of sticky oil, such as with a little oil and a small amount of oil on the 10th). It is recommended to use the following agents to prevent and treat
15% acetamiprid 800 times. The drug is currently the preferred pesticide for killing sucking pests. The control of Bemisia tabaci is cheap, effective, and cost-effective, and the insecticidal activity is higher than imidacloprid under cool autumn weather conditions. It is recommended that pesticides be mixed with other ingredients to reduce costs and improve efficacy.
225% buprofezin (buprofezin) 1000 to 1500 times. There is no direct killing effect on adult worms. Generally, they are effective 3 to 7 days after treatment, but they have a longer effective period. Need special attention is that the drug on cabbage, radish is easy to produce brown spots and green leaves and other phytotoxicity.
325% Aktai (thiamethoxam) 2500 to 5000 times. The rate of insecticide is slow, and the peak of dead insects is generally 2 to 3 days after application.
4 "Chenke 140" 3000x liquid + Nongxi 1 1000x liquid. According to the test of cotton farmers in Guangping County, the effect of the control of Bemisia tabaci can reach 90%, and it can simultaneously treat aphids, red spiders, beet armyworm, cotton bollworm, cabbage caterpillar, etc., and the effective period is 10 to 15 days.
5 Bayer's "Million Veteran" 4000 to 5000 times liquid. The composition of the drug is spirotetramat, which is a new type of pesticide with two-way systemic absorption and transmission properties. It mainly causes the death of larvae by interfering with the fat biosynthesis of insects. According to trials in Qingzhou and Liaocheng in Shandong province, one spraying period can last 15 to 20 days.
2. Special reminder:
1 "Treatment with early treatment" is the key to obtaining the best control effect. In the case of a low population density and a small worm age, prevention and control can have a multiplier effect.
2 It is very important to master medications in the evening for the weakness of their ability to fall in the evening. Also, attention should be paid to uniform and fine spray in order to increase the control effect and reduce the spread of debris.
3 Because the population density of B. tabaci is high and the generations overlap, it should be sprayed again 3 to 5 days after the application. And pay attention to alternate medication and rational compounding to avoid drug resistance.
4 Bemisia tabaci parasites and wings have a layer of wax paper white powder, spraying a small amount of neutral laundry detergent can be added in the preparation of a good solution (concentration does not exceed 0.05%) to enhance the insecticidal effect.
5 Pay attention to the reasonable application of phosphorus and potassium fertilizers, which can not only promote the high yield and quality of crops, but also reduce the infestation of whitefly.
