Embodiment
[0037] This embodiment provides a compound medicine for treating both underground pests and plant pathogenic nematodes, which is composed of active ingredients, fillers and auxiliary agents. The active ingredients include thionofos and also component A, which is Chlorpyrifos, phoxim, triazophos, diazinon, imidacloprid, avermectin, trichlorfon, phorate, carbofuran, cypermethrin, cis-cypermethrin, terbuthion, methylisosulfur Phosphorus, Bacillus thuringiensis, Beauveria bassiana, or entomopathogenic nematode, the ratio of the two parts by weight is 1:10-10:1, that is, the ratio of the parts by weight of thionphos to component A is 1 : Between 10 and 10:1. In order to improve the medicinal properties of the compound medicament in this embodiment, it is obtained through experiments in this embodiment that the weight ratio of thionphos to component A is between 1:4 and 1:2. Strong.
[0038] In this embodiment, according to the above ratio, the compound medicament is formulated into ...

Abstract
The invention discloses a compound medicament for treating both underground pests and plant pathogenic nematodes, which is composed of active ingredients, fillers and auxiliary agents. The active ingredients include sulfamidophos and component A, and the component A is chlorpyrifos , phoxim, triazophos, diazinon, imidacloprid, abamectin, trichlorfon, phorate, carbosulfan, cypermethrin, cis-cypermethrin, terbufos, isofenphos-methyl , Bacillus thuringiensis, Beauveria bassiana or entomopathogenic nematodes, the weight ratio of the two is 1:10-10:1. The present invention adopts the compound medicament for controlling subterranean pests and plant pathogenic nematodes with the above components, which can avoid repeated application of pesticides, reduce the amount of pesticides used, reduce the production cost of crops, reduce pesticide residues on crops, and reduce environmental pollution. degree.
Description
Technical field [0001] The invention relates to the field of pesticides, in particular to a compound medicine for curing underground pests and plant pathogenic nematodes. Background technique [0002] Nematode disease is one of the main diseases of crops in my country. It harms many types of crops and causes serious damage. According to statistics, the world's annual crop yield loss due to nematode disease is as high as 20-30%, about 100 billion US dollars. Because nematodes are soil-borne diseases and have a long time of damage, it is difficult to control, high cost of chemical control, and poor control effect. [0003] Nematode diseases mainly include sweet potato stem nematode disease, soybean cyst nematode disease and root knot nematode disease. In recent years, sweet potato stem nematode disease has occurred rampantly, and it is common in my country, with the most serious occurrence in Shandong, Hebei, Jiangsu and Henan. It severely restricts the production of sweet potato in ...
