Grape herbicide composition and using method thereof

Abstract

The invention relates to a chemical herbicide composition, in particular relates to a grape chemical herbicide composition and application thereof. The chemical herbicide composition is AB or AC type broad-spectrum systemic stem leaf herbicide taking haloxyfop-P (A), trifloxysulfuron sodium (B) and pyrazosulfuron (C) as effective ingredients, has the remarkable weeding effect, is safe to grapes, is free from phytotoxicity, and can be processed into a mixture or a companion agent, and also can be compatible with other ingredients; the grape chemical herbicide composition is characterized in that the effective ingredients A and B or A and C of AB or AC are used for preventing and eliminating weeds of different populations respectively, have no obvious synergism, and when the AB or AC is prepared, the A and the B or the A and the C are mixed on the basis of the standards of effective ingredients for preventing and eliminating the weeds respectively; a using method is flexible, the A, the B and the C can be sprayed separately, or the A and the B or the A and the C can be mixed, agricultural organosilicones also can be added and mixed to be sprayed for improving the herbicide effect, and the chemical herbicide composition can be directionally sprayed to the weeds in a penetrating manner in an early stage. According to the grape herbicide and the using method thereof, the high-efficiency management technology application in grape culture can be facilitated.

Description

[0001] technical field [0002] The invention relates to an agricultural chemical herbicide composition, in particular to a grape herbicide composition and its application. Background technique [0003] Chemical herbicides save labor and time, and do not damage crops. The use of chemical pesticides to control field weeds is an advanced technology in agricultural modernization and one of the powerful measures to increase agricultural production, which is of great significance to the development of agricultural production. Chemical weeding has been widely used in a variety of cultivated crops. Due to safety issues, it must be used with caution on some special plants, especially in viticulture, it has not been effectively and widely used. [0004] In the face of a large number of weeds that appear in the grape cultivation process, people often talk about whether to use herbicides, and look at the grass and sigh. This is because there are too many cases of herbicides causing ph...

Problems solved by technology

[0004] Faced with the large number of weeds that appear in the grape cultivation process, whether to use herbicides, people often talk about the color change and hope for the grass. This is because the herbicides There are too many cases of phytotoxicity caused to grape production, most of which are caused by the drift of herbicides (especially the herbicides 2,4-D butyl, 2-methyl-4-chloride, etc.) used by surrounding cultivated crops, and the losses are often very big

Simply put, herbicides are harmful to grapes when they smell them, and they are even more afraid of using herbicides. People are generally wary of using herbicides on grapes, which makes people afraid to use herbicides when they want to use them in viticulture.

[0005]Although there is no special herbicide for grapes from the applicable symbol plants of herbicides on the market, in order to give full play to the role of herbicides in grape production, it is necessary to solve the problem of weed In order to save manpower and reduce costs, people still use various methods to use herbicides very carefully, such as using paraquat, Roundup, glyphosate, atrazine, etc., but conditions require Very harsh, "atrazine" must be in the rain, when the soil humidity is about 75% to 80%, "paraquat, roundup, glyphosate, atrazine" must be in clear and windless weather For spraying, it is necessary to carry out directional spraying accurately, and it must not be sprayed on the grape leaves, otherwise it will cause serious injury, and even so, the phenomenon of phytotoxicity also occurs from time to time

This shows that the choice of herbicide is not good, and it is still harmful to the grapes, but people try to avoid it by all means, and there is a great risk in this method

[0006] Even so, in the existing chemical weeding application technology, there are limitations in the chemical weeding technology for grapes. In general, herbicides cannot control grasses, broadleaf Leaf and sedge weeds often kill one type of weed while another type of weed grows vigorously, and it cannot completely solve the weed damage

[0007] Therefore, in the face of grapes, an efficient and economical fruit tree, especially in large-scale plantations, people are still cautious when using herbicides, and still have to use a lot of manual weeding, However, we are also looking for chemical weeding methods through various channels, especially more and more people are making inquiries through the Internet, but they have not been able to get good answers.
