Problems solved by technology

Although this patent relates to herbicide fertilizers composed of the pesticide herbicides bensulfuron-methyl, mefenamide and nitrogen, phosphorus, potassium, zinc, and boron element fertilizers according to different components and contents, the safety, stability and efficacy of herbicide fertilizers are subject to various factors. Influenced by factors, especially closely related to its composition, yet, the optimal ratio of bensulfuron-methyl and mefenacet herbicidal efficacy has not been found in the prior art
In terms of preparation method, although the process is processed step by step, the powder mixing, granulation, drying and coating process is still used for the pesticide herbicide and fertilizer components, which has the following problems: 1) Pesticide herbicide (including safener) premixed powder Mixing with fertilizer ingredients directly powder and powder, the production process of medicinal fertilizer is too long, herbicide powder is difficult to control, causing serious environmental pollution; 2) Pesticide herbicide and fertilizer ingredients need to be dried at high temperature (110-120°C) for a long time 3) There are many key points in process control, complex operation, difficult quality control, affecting drug efficacy, etc.

Abstract

The invention discloses a benzyl pyridine. mefenacet herbicide fertilizer which is prepared by combining bensulfuron methyl and mefenacet pesticide herbicide with herbicidal activity and a nitrogenous fertilizer carrier, wherein the weight ratio of the bensulfuron methyl to the mefenacet is 1:16.5; and the nitrogenous fertilizer carrier consists of urea, ammonium chloride and filler. The invention further discloses a production method of the herbicide fertilizer; water is used as the solvent, and herbicide fertilizer grains are prepared by using a spraying capsule method. The herbicide fertilizer is short in process procedure, stable in quality and high in yield; the obtained herbicide fertilizer grains are suitable for fertilizing and weeding in rice fields, and the purposes of labor saving and time saving are achieved.

Description

Technical field [0001] The invention belongs to the field of pesticide herbicide fertilizers for paddy fields, and particularly relates to a benzylide·benzothiayl herbicide fertilizer and a production method thereof. Background technique [0002] With the acceleration of my country’s urbanization and urbanization, a large number of rural population and rural labor are transferred to cities, and agricultural production will develop in the direction of intensification, large-scale, and high-efficiency. Production methods and technologies that improve labor efficiency and resource utilization Measures will be paid more and more attention. Herbicide fertilizers scientifically integrate pesticide herbicides and carrier fertilizers into one, becoming a multi-functional "medicinal fertilizer" product, which has the effects of both fertilizer and pesticide. One application can complete two or more This process achieves double or multiple effects and realizes the purpose of saving labor a...
