Embodiment 1

[0016] A selective herbicide obtained by the following mass ratio: 1.5% of 2,4-D sodium, 30% of glyphosate ammonium salt, 0.19% of EDTA-2Na, 1.9% of auxiliary agent FH03, and the balance is ammonium sulfate.

Embodiment 2

[0018] A selective herbicide obtained by the following mass ratio: 3% 2,4-D sodium, 50% ammonium glyphosate, 0.4% EDTA-2Na, 3% additive FH03, and the balance is ammonium sulfate.

Embodiment 3

[0020] A selective herbicide obtained by the following mass ratio: 4% of 2,4-D sodium, 78.2% of ammonium glyphosate, 0.5% of EDTA-2Na, 5% of additive FH03, and the balance is ammonium sulfate.

[0021] Instructions:

[0022] Dilute this selective herbicide with water according to the recommended dosage during the vigorous weed production period, and then spray it on the stems and leaves of weeds. 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 and shrubs.

Abstract

The invention discloses a selective herbicide. The selective herbicide is prepared from the following components in mass percentage: 1.5-4% of 2,4-sodium drops, 30-78.2% of glyphosate ammonium salt, 0.19-0.5% of EDTA-2Na, 1.9-5% of an auxiliary FH03 and the balance of ammonium sulfate. The selective herbicide is a soluble granule type herbicide which is prepared by mixing 2,4-sodium and glyphosateammonium salt, has the characteristics of selective agents and quenching herbicides, has strong systemic property, has strong destructive power for underground tissues of perennial deep root weeds, and can be used to prevent weeds from arable lands. The selective herbicide has a good control effect on weeds which produce resistance due to perennial using of single-dosage glyphosate.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a selective 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 selective herbicide that ...
