Embodiment 1

[0026] Herbicides builders, formulation: 15% lecithin, 15% polyether siloxane, Vitamin E 0.05%, alkyl polyglycosides 10%, 10% silicone, 0.5% silicone defoamer, deionized water ad 100%.

[0027] In a method for preparing builder embodiments are: previously above components according to the formulation by weight weighed a good backup, first of deionized water into a stirred tank, and then into and polyether siloxane lecithin, vitamin E after stirring until completely dissolved, and alkyl polyglycosides into a silicone mixture for 30 minutes, a silicone antifoaming agent, mixing stirring was continued for 20 minutes.

[0028] Herbicide tank mix for use, reducing the amount of Herbicide, Example 1 was added 5 g Formulation amount proportional to the amount of builder is 1: 3000 (builder: herbicide), both mixed dilution of grass killing effect was significantly higher than the amount of the original treatment, a synergistic effect is obvious.

Embodiment 2

[0030] Herbicides builders, formulation: 10% lecithin, 15% polyether siloxane, Vitamin E 0.05%, methylated polyoxyethylene fatty acid 10%, 10% glycerol, 0.5 silicone defoamer % deionized water up to 100%.

[0031] Herbicide tank mix for use, reducing the amount of Herbicide, was added 5 g Formulation Example 2 The amount embodiment, the ratio between the amount of builder is 1: 3000 (builder: herbicide), both mixed dilution of grass killing effect was significantly higher than the amount of the original treatment, a synergistic effect is obvious.

Embodiment 3

[0033] Herbicides builders, formulation: 5% lecithin, 10% polyether siloxane, Vitamin E 0.1%, alkoxy esterified polyoxyethylene glycerin 10%, 10% tridecyl alcohol ester, polyether-based defoaming agent 0.8% deionized water up to 100%.

[0034] Herbicide tank mix for use, reducing the amount of Herbicide, 5 g Formulation Example 3 was added an amount embodiment, the ratio between the amount of builder is 1: 3000 (builder: herbicide), both mixed dilution of grass killing effect was significantly higher than the original amount of processing, synergistic effect is obvious.

Abstract

The invention belongs to the technical field of pesticides, and in particular relates to a herbicide synergist and its preparation method and application. The herbicide synergist is prepared by processing lecithin, polyether siloxane, vitamin E, spreading penetrating agent, surfactant, defoaming agent and deionized water. Improve the activity of herbicides and reduce the dosage of herbicides, thereby reducing environmental pollution and slowing down the resistance of weeds to herbicides.

Description

Technical field [0001] The present invention belongs to the technical field of pesticide, particularly herbicide, to a builder and a preparation method and application. Background technique [0002] Our herbicide industry from scratch, from small to large, progressive development, has formed a complete industrial system. In 60 years time, my country's herbicide industry have gone through a process of creation of Man from a reference to the introduction, from imitation to. According to statistics, since 1982, my country's implementation of its pesticide registration, registered with the Ministry of Agriculture has received herbicides (active ingredient) of nearly 200, more than 300 combinations of agents mix, the original drug formulations and products over 1500. Divided by selective herbicides kill range, Herbicide Class 2. Herbicide glyphosate (series), oxalyl sulfosate, glufosinate, bialaphos, paraquat, diquat, sulfometuron, sodium pentachlorophenol and the like, although a sma...
