Synergistic method for preventing and controlling weeds of weeding vinegar

Abstract

The invention relates to a synergistic method for preventing and controlling weeds of weeding vinegar and belongs to the field of a compound natural pesticide synergism technology and a usage method. The synergistic method for preventing and controlling weeds of the weeding vinegar comprises the following steps that 1, after the weeding vinegar is diluted with water, mineral oil accounting for 10-50% of the weight of the weeding vinegar is instantly added and is evenly stirred; 2, then a surfactant accounting for 0.5-5% of the weight of the weeding vinegar is added and is evenly stirred; 3, spraying is performed by using an electrostatic sprayer. The weeding vinegar has a promoting effect and is low in cost, accordingly does not easily form a large-tonnage consumption article and is used in common pollution-free food production. According to the method, the weeding vinegar, the mineral oil and the surfactant are packaged together in a bottling mode and are mixed in advance or poured in a separated mode according to the situation in use, accordingly the requirement for industrial applicability is met, the usage cost is greatly reduced, meanwhile a weeding effect is ensured, and the weeding vinegar is harmless while efficient weeding.

Description

Technical field [0001] The invention relates to a synergistic method for controlling weeds with herbicidal vinegar, and belongs to the field of synergistic compounding technology and use method of natural pesticide. Background technique [0002] Herbicide vinegar is a kind of bamboo and wood vinegar herbicide. It is a new natural herbicide using bamboo and wood vinegar as raw material. It has superior characteristics. For example, 1) Compared with glyphosate, bamboo and wood vinegar is safer and against non-targets. Biologically harmless and easy to be decomposed and utilized by microorganisms, it is safer for humans and the ecological environment; 2) Approved by the United States, Canada, Japan, European Union and other countries for organic agriculture; approved by China, reference basis: GB / T 19630-2011 "Organic Products 》Table A.2 Natural vinegar of plant and animal origin in plant protection products (such as: vinegar, wood vinegar and bamboo vinegar). Japan's organic certi...

Problems solved by technology

However, due to the high production cost, such as the production cost of more than 1,000 yuan per ton, the application cost exceeds 60 yuan per mu; now it can only be used in organic agriculture, an industry that only accounts for less than 1% of the agricultural market, how to increase the effect technically , Reducing the cost of use will determine whether the weeding vinegar can be used in ordinary agriculture (the field of pollution-free food production) that occupies 99% of the market. If the synergy is more than doubled, the application cost can be reduced to less than 30 yuan per mu, which will be compared with The price of the chemical herbicide glufosinate-ammonium is comparable, so it can enter the market on a large scale

[0003] In a word, the herbicide vinegar produced by concentrating bamboo and wood vinegar is a special herbicide used in organic agriculture, but it has the disadvantages of large dosage and high cost per mu.
