High Concentration Herbicide for Gramineae

Abstract

The present invention generally relates to herbicides, and more particularly to herbicide compositions suitable for plants of the Poaceae Scutellaria genus. A high-concentration herbicide suitable for plants of the Poaceae Scutellaria genus, the main feature of which is that the ratio (weight) of its raw materials is: glyphosate 35% to 85%; dipropazone 10% to 15%; Engine oil 4% to 52%. The advantage of the invention is that the herbicide does not need water, and has the characteristics of low pesticide application amount, stock solution spraying, high application efficacy and quick effect. The herbicide of the present invention has a killing rate of more than 92% for the plants of the genus Scutellaria. In plot tests, the killing rate of the present invention to stinky grass reaches 92% to 97.5%; in the small-scale test demonstration stage at the level of herdsmen, the killing rate of the present invention to stinky grass and stinky grass reaches 92% to 92%. 95.5%. After 5 years of killing stinky grass and stinky grass, under the natural state, the vegetation functional group structure of the degraded grassland can be restored to the state before the grassland degradation, and the grassland production capacity can be increased by 68% to 80%.

Description

Technical field: [0001] The present invention generally relates to herbicides, and more particularly to herbicide compositions suitable for plants of the Poaceae Scutellaria genus. Background technique: [0002] There are about 70 species of stinky plants in the world, distributed in the temperate regions of the northern and southern hemispheres. There are 9 species in my country, mainly distributed in northern grasslands. According to the survey, Melica przewalskyi Roshev, Melica radula Franch and Melica tibetica Roshev are mainly distributed in Gansu, Qinghai, Tibet and other places of my country. Smelly grass is a perennial herb of Gramineae with rhizomes. At the initial stage of invading the degraded grassland, the stinky grass spreads to the surrounding area in the form of clumps, and gradually forms a single stinky grass population patch with an area of ​​several square meters to several hectares. With the prolongation of the growth period of the community (about 20...

AI Technical Summary

Problems solved by technology

At present, the technical methods for controlling gramineous weeds generally have problems such as large amount of herbicides, need to be diluted with water, and slow spraying speed.

The present inventor discloses a formula suitable for herbicides of the genus Gramineae herbicide in the patent No. ZL2006128735.7 titled "Herbicides Suitable for Poaceae Scutellaria plants or malignant grasses with rhizomes", The main products are glyphosate, ethephon, and ethephon, and they need to be diluted with water. They are more suitable in areas with water, but in areas without water, the effect of this product is very poor and cannot be used.

[0003] There is no report on the use of glyphosate and glyphosate as pure pesticides
