Problems solved by technology

[0003] However, due to improper use, droplet drift, leaching, and liquid volatilization, chemical herbicides not only seriously affect the growth and development of crops, but also bring about an increase in the population of drug-resistant weeds, the emergence of weed resistance, residual poisons and phytotoxicity, and lower Stubble crop yield reduction, land degradation and other issues

preparation example Construction

[0026] The invention provides a preparation method of ammonium pelargonic acid weed-killing water emulsion, which uses plant-source pelargonic acid mother liquor as a raw material, and includes the following steps: S1: Add pelargonic acid and ammonia water into a metering tank respectively, and first put part of pelargonic acid into a reaction kettle , and drip ammonia water into the reaction kettle to keep the reaction evenly bubbling; then add water and the remaining nonanoic acid to the reaction kettle, and continue to drop ammonia water to obtain ammonium nonanoate; S2: prepare through step S1 Add emulsifier, preservative, penetrating agent, thickener, antifreeze and water to the obtained ammonium nonanoate, and stir evenly to obtain the ammonium nonanoate weeding water emulsion.

[0027] As a preferred embodiment, it includes the following steps: S1: Add pelargonic acid and ammonia water into the metering tank at a mass ratio of 1:0.5-1:1.5, and first put pelargonic acid f...

Embodiment 1

[0032] The preparation method of ammonium nonanoate weeding water emulsion comprises the following steps:

[0033]S1: Add nonanoic acid (99%) and ammonia water (25-28%) into the metering tank respectively, first put 84kg of nonanoic acid to be reacted into a 1000L reactor, turn on the temperature control of the reactor, and control the reaction temperature to 60°C. Start stirring and the rotating speed is 100rpm, and the flow rate of 2kg / min ammonia water is added dropwise with 80kg of ammonia water to keep the reaction evenly bubbling; then add 80kg of water to the reaction kettle, keep the stirring time for 20min, add the remaining 84kg of nonanoic acid, and continue Add dropwise the remaining 80kg of ammonia water until the pH of the reaction system is 8, stop stirring to obtain ammonium nonanoate;

[0034] S2: Add agricultural milk 1602#9.84kg, potassium sorbate 492g, agricultural organic silicon 6kg, magnesium aluminum silicate 2.46kg, glycerol 4.92kg to the ammonium nona...

Abstract

The invention discloses a preparation method of an ammonium nonanoate weeding emulsion in water, which takes plant-derived nonanoic acid mother liquor as a raw material and comprises the following steps: S1, respectively adding nonanoic acid and ammonia water into a metering tank, firstly adding part of nonanoic acid into a reaction kettle, dropwise adding ammonia water into the reaction kettle, and keeping uniform reaction and bubbling; then adding water and residual nonanoic acid into the reaction kettle, and continuously dropwise adding ammonia water to obtain ammonium nonanoate; and S2, adding an emulsifier, a preservative, a penetrant, a thickener, an antifreezing agent and water into the ammonium nonanoate prepared in the step S1, and uniformly stirring to obtain the ammonium nonanoate weeding emulsion in water. The herbicide prepared by the method disclosed by the invention is applied to non-cultivated land, orchards, forest land and crops before and after stubble, has the advantages of quick effect, wide weeding range, low residue, low toxicity, safety, environmental friendliness and the like, has great application and popularization value on organic crops, and is a novel environment-friendly herbicide product.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a preparation method of an ammonium nonanoate herbicide aqueous emulsion. Background technique [0002] Weeds are one of the most important factors leading to crop yield reduction, and the area of ​​land in China perennially affected by weeds exceeds 73 million hm 2 , The direct economic loss exceeded 90 billion yuan. Weed control is one of the major challenges faced in agro-ecosystems and urban lawn management. Chemical herbicides play a dominant role in today's weed control because of their rapid action, remarkable effect, and labor-saving and time-saving characteristics. In recent years, the use of herbicides in agricultural production has become more and more extensive, and the proportion of herbicides in the world's pesticide sales has exceeded 60%. Most of these herbicides are chemically synthesized high-efficiency or even super-efficient herbicides . [0003] Howeve...
