Embodiment 1

[0025] The embodiment of the present invention provides a slow-release medicinal fertilizer composition. The slow-release medicinal fertilizer composition comprises 0.1% pyraclostrobin, 0.1% metalaxyl, 0.5% polyglutamic acid, 5% sodium lignosulfonate, 5% Polyvinyl alcohol, 6% diatomaceous earth, 3% cornstarch, and make up to 100% with urea. The above-mentioned components are uniformly mixed with water, extruded and granulated, and dried to obtain a slow-release medicinal fertilizer composition product in the form of granules.

Embodiment 2

[0027] The embodiment of the present invention provides a slow-release medicinal fertilizer composition. The slow-release medicinal fertilizer composition includes 20% pyraclostrobin, 20% metalaxyl, 0.5% polyglutamic acid, 5% sodium lignosulfonate, 5% Polyvinyl alcohol, 6% diatomaceous earth, 3% cornstarch, and make up to 100% with urea. The above-mentioned components are uniformly mixed with water, extruded and granulated, and dried to obtain a slow-release medicinal fertilizer composition product in the form of granules.

Embodiment 3

[0029] The embodiment of the present invention provides a slow-release medicinal fertilizer composition. The slow-release medicinal fertilizer composition comprises 10% pyraclostrobin, 10% metalaxyl, 0.5% polyglutamic acid, 5% sodium lignosulfonate, 5% Polyvinyl alcohol, 6% diatomaceous earth, 3% cornstarch, and make up to 100% with urea. The above-mentioned components are uniformly mixed with water, extruded and granulated, and dried to obtain a slow-release medicinal fertilizer composition product in the form of granules.

Abstract

The invention relates to a slow-release pesticide-fertilizer composition and application thereof. The slow-release pesticide-fertilizer composition is prepared from the following components in percentage by weight: 0.1 to 20 percent of pyraclostrobin, 0.1 to 20 percent of metalaxyl-M, 0.5 to 1 percent of polyglutamic acid, 10 to 20 percent of pesticide adjuvant and 39 to 89.3 percent of fertilizer. The slow-release pesticide-fertilizer composition can slowly release pesticide and fertilizer in soil, meanwhile, effective components and the fertilizer promote absorption mutually, the internal absorption effect is improved, the fertilizer efficiency is very good, and meanwhile, the slow-release pesticide-fertilizer composition has a lasting prevention and treatment effect on downy mildew, powdery mildew, phytophthora root rot, pythium disease, gibberellic disease, fusarium wilt, gray mold and root rot. By applying the slow-release pesticide-fertilizer composition, the application amount of pesticides and chemical fertilizers can be reduced, so that the effects of reducing environmental pollution and alleviating land salinization are achieved.

Description

technical field [0001] The invention mainly relates to the field of agriculture, in particular to a slow-release medicinal fertilizer composition and its application. Background technique: [0002] Fungal disease is a disease that often occurs on crops, often causing symptoms such as necrosis, rot, wilting, etc., which has great hidden dangers to crop yield. At present, pesticides and fungicides are mainly used to prevent and control agricultural production. Due to the large amount of pesticides applied by farmers, it is difficult for crops to absorb in a short time, resulting in a large amount of waste of drugs. In order to prevent and control diseases, multiple applications are required. Such repeated applications are more harmful to the environment and groundwater. Therefore, it is necessary to A slow-release drug to achieve better efficacy and reduce the number of applications. [0003] Pyraclostrobin is a methoxyacrylate fungicide mitochondrial respiration inhibitor, a...
