Abstract

The invention provides a medicinal fertilizer and application thereof. The medicinal fertilizer comprises the following components in percentage by weight: 0.1 to 1 percent of abamectin, 1 to 20 percent of phoxim and / or chlorpyrifos, 15 to 40 percent of macro-element fertilizer, 1 to 5 percent of micro-element fertilizer and 34 to 72.4 percent of carrier. In the medicinal fertilizer, the abamectin, the phoxim and / or the chlorpyrifos, the macro-element fertilizer and the macro-element fertilizer are compounded so that the pesticide effects of the abamectin and the phoxim and / or the chlorpyrifos on nematode or / and underground insects are enhanced effectively and the medicinal fertilizer acts growth effect on crops. The medicinal fertilizer has excellent performance and pesticide effect so that the medicinal fertilizer can be applied in the prevention and control of the underground insects or / and nematode. The invention also provides a method for preparing a particle medicinal fertilizer and a powder medicinal fertilizer. The preparation method has the advantages of simple process, easily-controlled condition and suitability for industrialized production.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, and in particular relates to a medicinal fertilizer and its application, a preparation method of a granule-form medicinal fertilizer and a powder-form medicinal fertilizer. 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. Afte...
