Problems solved by technology

Coupled with the large-scale planting of herbicide-resistant transgenic crops, the ecology has changed to a certain extent, and it has accelerated the transformation of some weeds with similar genes to glyphosate-resistant genes, resulting in the inability of existing herbicides to weeds. make a good cleanup

Embodiment 1

[0015] A total herbicide, obtained by the following mass ratio: 5% sodium dimethyltetrachloride, 88% ammonium glyphosate, 1% EDTA-2Na, 4% auxiliary agent FH01, and the balance is ammonium sulfate .

Embodiment 2

[0017] A total herbicide, obtained by the following mass ratio: 2.5% sodium dimethyltetrachloride, 30% ammonium glyphosate, 0.3% EDTA-2Na, 1.3% auxiliary agent FH01, and the balance is ammonium sulfate .

Embodiment 3

[0019] A total herbicide, obtained by the following mass ratio: 3% sodium dimethyltetrachloride, 60% ammonium glyphosate, 0.6% EDTA-2Na, 2.5% auxiliary agent FH01, and the balance is ammonium sulfate .

[0020] Instructions:

[0021] After diluting the herbicide with water according to the recommended dose during the vigorous weed production period, spray it on the stems and leaves of the weeds in a directional manner. Do not apply pesticides when there is strong wind or rain is expected within half an hour. When the temperature is above 5°C, it can effectively control all types of weeds.

[0022]

[0023] Product use effect:

[0024] 1. The weeds began to wilt on the third day after spraying, showing obvious effects. The whole plant of the weeds died from leaves to roots within half a month. The plots where the product has been used have no weeds turning green within 3 months. It has a good control effect on malignant weeds resistant to long-term use of glyphosate sin...

Abstract

The invention discloses a non-selective herbicide, comprising the following components in percentage by weight: 2.5%-5% of MCPA-Na, 30%-90% of glyhosate ammonium, 0.3%-1% of EDTA-2Na, 1.3%-4% of an auxiliary agent FH01 and the balance of ammonium sulfate, concretely 5% of MCPA-Na, 88% of glyhosate ammonium, 1% of EDTA-2Na, 4% of an auxiliary agent FH01 and the balance of ammonium sulfate. MCPA-Naand glyhosate ammonium are mixed into soluble powder herbicides, with characteristics of both selective herbicides and non-selective herbicides, with strong internal absorption and strong destructivepower on underground tissues of perennial deep-rooted weeds, and can be used to control weeds in the uncultivated area. It has a good control effect on the weeds which are resistant to glyphosate single agent due to using the glyphosate single agent all the year round.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a total herbicide. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to destroy or inhibit plant growth. [0003] Glyphosate is the most widely used non-selective herbicide in the world. Due to long-term use, some weeds have developed certain resistance. Coupled with the large-scale planting of herbicide-resistant transgenic crops, the ecology has changed to a certain extent, and it has accelerated the transformation of some weeds with similar genes to glyphosate-resistant genes, resulting in the inability of existing herbicides to weeds. Makes for a good cleanup. Contents of the invention [0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: how to provide a herbicide that can better rem...
