Problems solved by technology

[0002] The current method of controlling weed damage mainly relies on the use of herbicides. However, a large number of herbicides cause soil and water pollution, weed resistance, crop damage, and pesticide residues in agricultural products. How to develop an environmentally friendly, safe, especially It is a technical problem faced by those skilled in the art to be a herbicide that has a wide herbicidal spectrum and does not harm crops
[0003] In addition, weed control is the main problem in the green belt of hosta interplanted with shrubs, and the weed control is not timely, which seriously affects the beauty of the green landscape
However, due to the unavoidable problem of pesticide damage to crops by spraying, only manual weeding can be used in greening work. Generally, it needs to be pulled out once every 15-20 days, and it needs to be done 8-10 times a year in northern areas; Maintenance work poses enormous difficulties

Embodiment 1

[0036] The present embodiment provides a kind of herbicide (granule), is made up of the composition of following parts by weight:

[0037]

[0038] The preparation method of described herbicide comprises the steps:

[0039] (1) Dilute the binder with 5 times the mass of water and mix it with the carrier, then add metolachlor to obtain mixed granules;

[0040] (2) Spray evenly the xylene solution in which oxyfluorfen is dissolved on the surface of the mixed particles, place in a ventilated and cool place, and wait for the xylene to volatilize to obtain the product.

Embodiment 2

[0047] The present embodiment provides a kind of herbicide (granule), is made up of the composition of following parts by weight:

[0048]

[0049] The preparation method of described herbicide comprises the steps:

[0050] (1) Dilute the binder with 5 times the mass of water and mix it with the carrier, then add metolachlor to obtain mixed granules;

[0051] (2) Spray evenly the xylene solution in which oxyfluorfen is dissolved on the surface of the mixed particles, place in a ventilated and cool place, and wait for the xylene to volatilize to obtain the product.

Abstract

The invention relates to the technical field of weeding, in particular to a herbicide composition and a herbicide and a preparation method and application thereof. The herbicide composition comprisesthe following effective components: metolachlor and oxyfluorfen, wherein the mass ratio of the metolachlor to the oxyfluorfen is (5-10): (1-10). The herbicide comprises the herbicide composition, preferably, the dosage form of the herbicide is granules. The two effective components (metolachlor and oxyfluorfen) of the herbicide composition are in synergistic interaction so that the herbicide composition has the effects of environmental protection and safety, particularly has the effects of high efficiency and wide herbicide controlling spectrum and exceeds the use of two single-dose varieties,namely metolachlor and oxyfluorfen. The herbicide composition is safe to crops, low in cost and good in control effect. The herbicide avoids damage of herbicide spray to leaves and effectively prevents and removes gramineous weeds and broadleaf weeds. The herbicide is simple and convenient to weed, labor-saving and time-saving.

Description

technical field [0001] The invention relates to the field of herbicide technology, in particular to a herbicide composition and herbicide as well as a preparation method and application thereof. Background technique [0002] The current method of controlling weed damage mainly relies on the use of herbicides. However, a large number of herbicides cause soil and water pollution, weed resistance, crop damage, and pesticide residues in agricultural products. How to develop an environmentally friendly, safe, especially It is a technical problem faced by those skilled in the art to find a herbicide that has a broad herbicidal spectrum and does not harm crops. [0003] In addition, weed control is the main problem of the green belt of hosta interplanted with shrubs, and the weed control is not timely, which seriously affects the beauty of the green landscape. However, due to the unavoidable problem of pesticide damage to crops by spraying, only manual weeding can be used in green...
