Background
Fructus Siraitiae Grosvenorii fruit has effects of clearing heat and detoxicating, moistening lung and relieving asthma, eliminating phlegm and relieving cough, refreshing and promoting fluid production, and has certain effects of preventing and relieving diabetes, treating coronary heart disease, etc. For a long time, in the planting process, the root of the momordica grosvenori is easy to be affected by root knot nematode, so that growths of momordica grosvenori plants and fruits are poor, the result quantity is greatly reduced, and the economic benefit of planting the momordica grosvenori is influenced. Researches report that the incidence rate of the root-knot nematodes of the momordica grosvenori reaches more than 86% under the condition that nematicides are not used, and after the momordica grosvenori plants are affected by the root-knot nematodes, soil-borne diseases such as fusarium wilt, root rot and the like are serious, so that compound invasion is caused. The yield of the momordica grosvenori can be reduced by 60-70% under the influence of the invasion of the root knot nematode disease, and the development of the momordica grosvenori industry is severely restricted.
In Guangxi, the Siraitia grosvenorii root-knot nematodes are mainly southern root-knot nematodes (Meloidogyne incognita) and Java root-knot nematodes (Meloidogyne javanica), wherein southern root-knot nematodes are dominant populations. The chemical agent is an effective and convenient way for preventing and controlling the root-knot nematode, but the drug resistance of pests is rapidly accumulated due to the unreasonable use of a single chemical agent for a long time, so that the preventing and controlling effect of the chemical agent on the pests is reduced. The screening of the compound formula with synergistic effect on the root-knot nematodes can provide support for developing and developing efficient medicaments for preventing and treating the root-knot nematodes.
Ivermectin, alias: ivermectin, CAS:70288-86-7, molecular formula: c (C) 48 H 74 O 14 The structure is as follows
The inventor finds that when ivermectin and chlorfenapyr, iprodione or prothioconazole are compounded through indoor experiments, the ivermectin and iprodione compound pesticide has a synergistic effect on southern root-knot nematodes, and can provide support for developing and developing high-efficiency medicaments for preventing and treating the root-knot nematodes.
