Embodiment approach

[0026] In the following technical scheme, the active ingredient A is selected from malathion, the active ingredient B is selected from chlorfenapyr, the active ingredient C is selected from buprofezin, and the active ingredient D is selected from sulfoxaflor.

[0027] In one of the embodiments of the present invention, the A malathion is an emulsifiable concentrate, which is a product of Dezhou Lvba Fine Chemical Co., Ltd., and the active ingredient content is 70%; The product of Biotechnology Co., Ltd. has an active ingredient content of 30%; C Buprofezin is a suspension concentrate, a product of Jiangsu Wrigley Agrochemical Co., Ltd., and the active ingredient content is 37%; D Sulfoxaflor is a suspension concentrate, a product of Jiangsu The product of Suzhou Jiahui Chemical Co., Ltd., with an active ingredient content of 22%.

Embodiment 1

[0028] Example 1 Preliminary test on the control of oak garden pests.

[0029] Before carrying out the pest control in the oak garden, carry out relevant pre-experiments in the laboratory. The test was completed in the test base of Sericulture Science Research Institute of Liaoning Province. The drug components were A, A B, A C, AD, and the concentration of the tested drug was 0.35 g to 3.5 g of malathion in 15 L of water. In a disposable lunch box, 5 black scapula and 10 1-2 instar tussah silkworms were placed respectively, with 2 replicates for each treatment. The room temperature is 25°C, the relative humidity is 70%, and the temperature is 27°C during the outdoor test. 24 hours after spraying the pesticide, the control effect was investigated. Spraying water was used as the control treatment. Correction control effect is statistically calculated according to conventional experimental methods.

Embodiment 2

[0033] Example 2 Prevention and treatment of black broad-shouldered carapace in the oak garden.

[0034] The test was carried out in the oak garden in Xiuyan County, Anshan City, Liaoning Province in August 2019. Use once during the occurrence period of black broad shoulder beetle adults. Spray evenly with a knapsack-type manual sprayer. On the oak trees, there are mainly black-shouldered beetle adults, concave-winged broad-winged beetle larvae, and a small amount of stinkbugs, stinkbugs, silkworm katydids, and leaf-eating pests. The day of spraying is fine, and the average The temperature was 29.5°C; there was no rain for 2 days after the medicine. 24 hours to investigate the effect of prevention and control. Correction control effect is statistically calculated according to conventional experimental methods.

Abstract

The invention relates to the field of pesticide application, in particular to application of malathion as an effective component in prevention and control of pests (tussah pests and oak pests) in a tussah garden. The malathion pesticide provided by the invention can be prepared into missible oil, a suspending agent, wettable powder, water dispersible granules, emulsion in water, powder, granules and other dosage forms by adopting a method known by technicians in the field. The malathion pesticide provided by the invention is suitable for effectively preventing and treating predatory and phytophagous pests with chewing mouthparts, hemiptera mouthparts and sponging mouthparts, such as coleoptera, hemiptera, lepidoptera, diptera, homoptera, orthoptera, mantis, hymenoptera and spider in the tussah garden on the premise of ensuring the safety of tussah; the malathion pesticide is especially suitable for preventing and treating black wide-shoulder step beetles, concave-wing wide-jaw step beetles, arma chinensis, longhorned grasshopper and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide applications, in particular to the application of pesticides with malathion as an active ingredient to prevent and control pests in tussah gardens in tussah silkworm production. Background technique [0002] Oak leaves are the favorite food of tussah silkworms. Tussah silkworm is a kind of wild silkworm with important economic value. The growth and development stage of its larvae is completed on the oak trees in the oak garden. In the natural environment in the wild, pests in the tussah garden (tussah pests, oak tree pests) pose a serious threat to the normal growth and development of tussah silkworms, such as: black broad-shouldered carapace, concave-winged broad-jawed carapace, stinkbug, stinkbug, and silkworm The invasion of tussah silkworms by predatory pests such as katydids, and the competition between tussah tree pests and tussah silkworms for eating tussah leaves have seriously affected...
