Problems solved by technology

[0009] Insecticide varieties containing a single active ingredient often have varying degrees of defects in the control of agricultural pests: pests are prone to develop resistance after continuous use, and frequent use will aggravate environmental pollution
[0010] However, there is currently no relevant patent record of an insecticidal composition containing both spinosyn and thiamethoxam as active ingredients

Embodiment 1

[0034] Insects to be tested: rice white-backed planthopper, reared artificially for 3 generations and used for later use.

[0035] The test agent: provided by Guangxi Tianyuan Biochemical Co., Ltd.

[0036] Experimental design: Through preliminary experiments, the effective lethal concentration ranges of spinosad, thiamethoxam, and their mixtures with different ratios were determined, and five gradient concentration treatments were designed for each drug according to the content of active ingredients. The blank treatment of the original drug was used as a control.

[0037] Test method: During the test, the mother liquors of spinosad, thiamethoxam, and each compounding agent were diluted to the following 5 series of concentrations, and placed in beakers for later use. Using the method of spraying first and then inoculating insects, spray the diluent on the rice at the peak tillering stage of the same size that has not been exposed to any pesticides, put it into the insect bree...

Embodiment 2

[0051] Example 2: 24% spinosad thiamethoxam (4: 20) water dispersible granules control rice planthopper efficacy test

[0052] Spinosad 40 grams, thiamethoxam 200 grams, polyether 2 grams, white carbon black 150 grams, BIT (1,2-benzisothiazolin-3-one) 70 grams, AEO-535 grams, 130 grams of kaolin, 373 grams of ammonium sulfate, after mixing evenly, enter the airflow and pulverize, spray about 180 grams of kneading agent deionized water into the mixer, adjust the extrusion equipment, carry out extrusion granulation, and bake at 50-80 ° C After drying until the moisture content is acceptable, a 24% spinosyn-thiamethoxam composition water-dispersible granule can be prepared. After the proportion is diluted by 3750 times, it is evenly sprayed, and the effect of controlling rice planthopper 72 hours after the application is 95.73% to 98.12%. Times and 2500 times of use, the 72-hour control effect is 81.17% and 72.22% respectively. In the test, the inventor did not find that the te...

Embodiment 3

[0053] Example 3: 11% spinosad thiamethoxam (1: 10) wettable powder control rice planthopper efficacy test

[0054] 10 grams of spinosad, 100 grams of thiamethoxam, 20 grams of polycarboxylate, 20 grams of alkylphenol polyoxyethylene, 20 grams of sodium lauryl sulfate, 20 grams of wetting penetrant F, white carbon black The mixture of 320 grams and 490 grams of diatomaceous earth was jet milled to obtain 11% spinosad-thiamethoxam wettable powder. The formula is diluted and sprayed by 2500 times, and the effect of controlling rice planthopper is 95.32%-97.15% within 72 hours after spraying. 25% thiamethoxam water-dispersible granules and 60 g / L spinosad composition suspension were diluted 2500 times and 1500 times respectively according to the same method, and the control effects were 87.25% and 52.27% respectively in 72 hours after the drug . In the test, the inventor did not find that the test agent had adverse effects on crops, and the agent was safe to natural enemy insec...

Abstract

The invention relates to a pesticide composition containing spinetoram and thiamethoxam. The active ingredients of the pesticide composition are spinetoram and thiamethoxam in a weight ratio of (1-50):(50-1), (1-20):(20-1) or (1-10):(10-1). When added with a corresponding aid and a filler, the pesticide composition containing spinetoram and thiamethoxam can be prepared into wettable powder, water dispersible granules, suspension, microcapsule suspension, missible oil, microemulsion and water emulsion respectively; and the pesticide composition containing spinetoram and thiamethoxam is used for preventing and controlling lepidopterous pests, homopterous pests and pests of thysanoptera in turfs and various crops such as grain crops, fruit trees and vegetables.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing spinosyn and thiamethoxam. Background technique [0002] At present, for the control of pests that are prone to resistance in agriculture, the main method is to develop new ingredients that have no cross-resistance with existing varieties or the compounding of existing pesticide varieties. The former is due to the high development cost and long cycle required. And the current development speed is far behind the speed of pest resistance. Therefore, it is the best choice to mix existing pesticide varieties with different action mechanisms. If the ratio is reasonable, it can produce a significant synergistic effect, making the field control effect significantly better than the effect of each single agent. Insecticides containing a single active ingredient often have certain defects in the control of agricultural pests. Continuous use for multiple times ...
