Abstract

The agricultural composition for preventing and controlling nematode contains nematicide and chitin. It has the double effects of killing nematode and raising plant immunity and thus has obvious effect of preventing and controlling nematode. The present invention also relates to agricultural composition comprising the nematicide composition and fertilizer with the functions of purifying soil, raising plant resistance, providing plant with nutrients and preventing and controlling nematode and diseases.

Description

【Technical field】 [0001] The invention relates to a nematicide-killing composition containing a nematicide and a chitin substance. Since the nematicide-killing combination has two functions of killing nematodes and increasing plant immunity, the effect of nematode control is very obvious. In addition, the present invention also relates to an agricultural composition consisting of the nematicide composition and a fertilizer. The agricultural composition has multiple functions of purifying and cleaning soil, improving stress resistance of plants, supplying nutrients required by crops, preventing insects and curing diseases, and the like. 【Background technique】 [0002] Plant parasitic nematodes are one of the infectious pathogens of plants. They are widely parasitic on the roots, stems, leaves, flowers, buds and seeds of various plants, causing various nematode diseases in plants. The vast majority of plant parasitic nematodes are hermaphroditic, that is, both male and female...
