Root knot nematode disease control medicine for crops

Abstract

The invention discloses a root knot nematode disease control medicine for crops. Raw materials of the medicine provided by the invention comprise, by weight, 20-40 parts of allyl isothiocyanate, 1-2 parts of a biological nematicide, 1-3 parts of chlorothalonil, 0.005-0.007 part of nimbin A, 0.05-0.2 part of nimbin B, 0.3-0.5 part of nimbin C and 20-30 parts of herb residue. The medicine provided by the invention has an excellent insecticidal effect on root-knot nematode and is low-cost. A method for preparing the medicine is simple. The medicine is friendly to the environment and crops and is pollution-free.

Description

technical field [0001] The invention relates to the technical field of ethylene-propylene rubber materials, in particular to a low-expansion ethylene-propylene rubber material. Background technique [0002] Root-knot nematode is a highly specialized plant pathogenic nematode with a wide range of hosts and many types of hosts. The nematodes mainly harm the roots of various vegetables, and form spherical or conical white nodules of different sizes on the young roots, some of which are bead-shaped. The aboveground part of the damaged plant grows short and slow, with abnormal leaf color, few fruits, low yield, and even causes early death of the plant, and while harming vegetables, it may aggravate the occurrence of soil-borne diseases such as root rot, greatly reducing the quality of vegetables , directly affects farmers’ income, and greatly restricts the development of agricultural production. At present, for root-knot nematode control of crops, soil treatment agents with high...

AI Technical Summary

Problems solved by technology

The aboveground part of the damaged plant grows short and slow, with abnormal leaf color, few fruits, low yield, and even causes early death of the plant, and while harming vegetables, it may aggravate the occurrence of soil-borne diseases such as root rot, greatly reducing the quality of vegetables , directly affects farmers’ income, and greatly restricts the development of agricultural production. At present, for root-knot nematode control of crops, soil treatment agents with high toxicity and damage to the ecological environment are mostly used, such as methyl bromide, dibromopropane, and chloropicrin. The disadvantages are It is inconvenient to use, unsatisfactory and dangerous, and has certain pollution to the environment; products such as abamectin and abamectin have disadvantages such as high cost of use, strong resistance, and short-lasting effect; other physical control methods include high temperature, water flooding, etc. , deep turning, etc. have problems such as incomplete effect, high cost, and difficult operation.
