Ascorbic acid and pyraclostrobin containing crop bactericide

Abstract

The invention discloses an ascorbic acid and pyraclostrobin containing crop bactericide. Not only can growth requirements of crops be met, but also the effects of sterilization, disease removal and control and the like are achieved, and moreover, remarkable yield increasing effects on multiple crops are achieved. According to the technical scheme, the crop bactericide is prepared from the following raw materials in percentage by weight: 0.001 to 90 percent of the ascorbic acid, 0.1 to 85 percent of the pyraclostrobin, 1 to 15 percent of a dispersing agent, 0.5 to 15 percent of a co-solvent, 0 to 5 percent of a stabilizer, 10 to 98 percent of a solvent and the balance of distilled water. A composition prepared by the invention is wide in application range, and has remarkable sterilization, yield increasing and income increasing effects on the crops, and has broad market development prospect and great social benefits and economic benefits.

Description

technical field

[0001] The invention belongs to the technical field of agriculture, and in particular relates to a crop fungicide containing ascorbic acid and pyraclostrobin and a preparation method. Background technique

[0002] In recent years, in order to obtain high-yield crops, vegetables, and fruits, excessive use of pesticides and chemical fertilizers has resulted in excessive chemical fertilizers and pesticide residues in agricultural products, soil and water pollution, and caused a series of environmental damage and ecological disasters. Serious threat to human survival and development. In response to these problems, some bio-organic fertilizers and pesticides have been developed at home and abroad. An organic mixture formed during the dry distillation of plant material that has a variety of biological effects. Japan used it as a feed additive, soil deodorant and organic fertilizer starter at the end of the last century. The effects of these substances on the ger...

Examples

Embodiment 1

[0025] Example 1: Formula: 0.001 kg of ascorbic acid, 85 kg of pyraclostrobin, 1 kg of dispersant, 0.5 kg of co-solvent, 5 kg of stabilizer, 10 kg of solvent, and distilled water as the balance.

[0026] Preparation method, the steps are as follows:

[0027] The preparation method is:

[0028] (1) Stir the stabilizer evenly, crush it into fine powder, pass through a 100-mesh sieve, and set aside. The stabilizer is prepared from sodium alginate, microcrystalline cellulose and modified starch in a mass ratio of 3:1:0.1 ;

[0029] (2) Add pyraclostrobin into the stainless steel autoclave, then slowly add ascorbic acid and dispersant, heat in airtight to 75°C, stir for 9 hours, then add distilled water, co-solvent and solvent and the treated product in step (1) Stabilizer, keep the temperature at 33°C, continue to stir for 35 minutes to obtain a mixed solution, and use it for later use. The dispersant is prepared from sodium tripolyphosphate and monoglyceride stearate at a mass ...
