Abstract

The invention relates to a pesticide-added fertilizer containing avermectins and oligosaccharide and a preparation method thereof. The pesticide-added fertilizer which is used for preventing and controlling underground pesticides and wireworms comprises the following components in percentage by weight: 0.1 to 1 percent of avermectins, 0.1 to 1 percent of oligosaccharide, 5 to 20 percent of macroelement fertilizer and 0.5 to 2 percent of microelement. The fertilizer is mainly processed into granules and soluble powder for preventing and controlling the underground pesticides and the wireworms of the corn, wheat, soybean, peanut and vegetable crops in the modes of seed dressing, spraying, seed fertilization, fertigation, leaching fertilization and the like and has the effect of increasing the crop yield.

Description

technical field [0001] The invention relates to a medicinal fertilizer for preventing and controlling underground pests and nematodes and a preparation method thereof Background technique [0002] Plant parasitic nematodes occur and cause damage in many countries and regions in the world, and there are various types. Globally, the occurrence and damage of plant parasitic nematodes are becoming more and more serious with the development of agriculture and forestry and the change of farming system. It is estimated that the annual loss rate of the world's major crops caused by plant parasitic nematodes is 12.3%, exceeding 100 billion US dollars, and the actual loss far exceeds the estimate. At present, there are about 3,000 kinds of nematodes harmful to plants. In my country, there are mainly root-knot nematodes, cyst nematodes, pine wood nematodes, and sweet potato stem nematodes. After the occurrence of nematode diseases, the yield is generally reduced by about 10%, and in ...
