Embodiment 1

[0022] 2-Hydroxy-4-oxo-3-phenyl-1-(2,2,2-trifluoroethyl)-4H-pyrido[1,2-a]-pyrimidinium inner salt (compound A) and insecticidal ring (compound B) are prepared into soluble powders according to different weight ratios (the preparation method can refer to Example 2), diluted with water, and prepared into mixture solutions of different ppm concentrations, and compound A and compound B are also prepared separately into soluble powder. Taking the apple peach aphid as the object, spraying was used to kill directly. According to the method of calculating the joint toxicity of the mixture through the toxicity index proposed by Sun Yunpei et al., the co-toxicity coefficient of the two active ingredients in the composition was tested. The specific results are as follows:

[0023]

[0024]

[0025] From the above experiments, it can be concluded that when compound A and compound B are applied to apple peach aphid pests in combination, when the weight ratio of the two active compon...

Abstract

The invention relates to an insecticidal synergistic composition containing thiocyclam. The composition comprises two active ingredients of 2-hydroxyl-4-oxo-3-phenyl-1-(2,2,2-trifluoroethyl)-4H-pyridino[1,2-a]-pyrimidine ylid and thiocyclam, wherein the two active ingredients present in a ratio of synergistic effective quantity; in particular, the weight ratio of the two active ingredients in thecomposition is 1:(0.01-100); the application quantities of the pesticides can be respectively reduced under the circumstance that the same control effects are reached while two pesticide active ingredients are mixed in use; and the two pesticide active ingredients show synergistic actions while killing pests.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and in particular relates to an insecticidal pesticide composition and its application, in particular to an insecticidal synergistic composition containing an insecticidal ring and its application for controlling crop pests. Background technique [0002] Insecticidal ring is a nereistin insecticide, which has contact killing and stomach poisoning effects, and also has certain systemic and fumigation effects, and can kill eggs. The toxic effect on pests is relatively slow, and those with mild poisoning can sometimes revive. It disappears quickly in the body, the residual effect period is short, and the residue in the crops is very small when harvested. The insecticidal ring has a good effect on pests of Lepidoptera, Coleoptera and Homoptera, and can be used for various pests on rice, corn, sugar beets and vegetables, but it is highly toxic to silkworms. [0003] Pyrimidinium compounds They a...
