Embodiment 1

[0062] Respectively, the original drug of cyclopyrid and isoprocarb was formulated with DMF into 5 series concentrations of 2 single agents and 5 groups of mixing ratios, and the specific ratio of the 5 series concentrations (cyclopyrid / isoprocarb Wei) are 1 / 3, 1 / 6, 1 / 9, 1 / 12, 1 / 15 respectively. The mid-third instar rice planthopper nymphs were treated with these serial concentrations of pesticides and a single spray method, and the nymph mortality of each treatment was recorded after 3 days. Results Sun Yunpei's method was used to calculate the toxicity index and co-toxicity coefficient.

[0063] The specific calculation method is as follows:

[0064] Standard Pharmacy LC 50

[0065] Actual Toxicity Index (ATI) =———————————

[0066] Test drug LC 50

[0067] Theoretical mixture toxicity index (TTI) = toxicity index of A × content of A in the mixture (%) + toxicity index of B × content of B in the mixture (%)

Embodiment 2

[0078] Weigh 15% cyclopyrid, 45% isoprocarb, 3% sodium lauryl sulfate, 7% calcium lignosulfonate, 4% white carbon black, 6% dipotassium hydrogen phosphate, soluble starch 1%, kaolin supplemented to 100%.

[0079] The components are mixed according to the weight ratio, mixed with air flow, crushed with water, added to the granulator for granulation, and then dried and sieved to obtain 60% cyclopyrid-isoprocarb water-dispersible granules .

Embodiment 3

[0081] Weigh 15% of cyclopyridam, 35% of isoprocarb, 8% of calcium lignosulfonate, 2% of sodium lauryl sulfate, 3% of dipotassium hydrogen phosphate, 6% of white carbon black, kaolin supplemented by weight percentage to 100%.

[0082] Calcium lignosulfonate is initially pulverized, each component is mixed according to the weight ratio, and then pulverized in a jet mill, and the obtained is 50% cyclopyrid-isoprocarb wettable powder.

[0083] The cyclopyrid-isoprocarb wettable powder prepared in this example was subjected to a field efficacy test for controlling wheat aphids. The results are shown in Table 2.

Abstract

The present invention provides a cycloxaprid and isoprocarb pesticide composition, wherein cycloxaprid and isoprocarb are compounded so as to provide a synergy effect and substantially reduce a cycloxaprid use amount, such that a drug cost is substantially reduced. In addition, the pesticide is prepared through compounding two insecticides with different action mechanisms, such that pest resistance is not easily generated.

Description

technical field [0001] The invention relates to a pesticide and insecticide, in particular to an insecticide for homopteran pests and lepidopteran pests. Background technique [0002] Homoptera is a relatively large group of insects. There are more than 45,000 known species of Homoptera in the world, and more than 3,000 species are known in China, mainly including cicadas, moth cicadas, leafhoppers, hornhoppers, and wax cicadas. Cicadas, planthoppers, psyllids, whiteflies, aphids and scale insects, etc. Homoptera insects all feed on plant sap, many of which can spread plant virus diseases and are important agricultural pests. [0003] Lepidoptera is the second largest order in Insecta after Coleoptera. About 200,000 species are known in the world, and more than 8,000 species are known in China. The distribution range is extremely wide. Most types of larvae are harmful to various cultivations Plants, the larger ones often eat the leaves or drill into the branches, and the s...
