Abstract
The invention relates to a weed-killing composition and a weed-killing method for an onion field. The weed-killing composition is missible oil and comprises the following components in percentage by weight: 30 to 45 percent of haloxytop-R-mithyl, 15 to 22 percent of lactofen, 7 to 9 percent of emulsifier, 2 to 4 percent of penetrant and the balance of dimethylbenzene. The weed-killing composition has good weed-killing effect, can kill weeds of the grass family and effectively kill broadleaf weeds, increases weed-killing broad spectrum, has low toxicity and residue, is convenient to operate, saves labor and money, reduces pollution to environment and reduces the burdens of farmers.
Description
Technical field
The present invention relates to a kind of onion field weeding composition and herbicidal methods.
Background technology
Onion field crop smothering kind is many, take place early, generating capacity is big, the harm phase is long, thereby the difficulty of preventing and kill off is also bigger.Adopt chemical weed control, it uses kind, use age and dosage must be very accurate, does to such an extent that bad meeting produces poisoning.
Haloxyfop-r-methyl, the scope of application is wide, broad weed-killing spectrum, lasting period is long, and the mu consumption is few, and is active high, can use with multiple mixture of herbicides, enlarge and kill the grass spectrum, improve drug effect, easy to use, but both bud pre-treatments, but bud post processing again, toxicity is low, but it is inoperative to broad leaved weed only to removing grass family class weeds.
Summary of the invention
The purpose of this invention is to provide a kind of onion field weeding composition and herbicidal methods, make the weeding in onion field more thorough, safe, reliable.
The present invention is achieved by the following measures:
Herbicidal combinations of the present invention is a missible oil, and its proportioning is (in a weight portion):
Haloxyfop-r-methyl 30%～45%
Restrain wealthy pleasure 15%～22%
Emulsifier 7%～9%
Bleeding agent 2%～4%
Dimethylbenzene supplies 100%
Using method:
During seedling 3-4 leaf, this Herbicidal combinations is mixed even spraying with water.
Useful fruit of the present invention is: this a kind of onion field weeding composition and herbicidal methods herbicidal effect are good, not only can remove grassy weed, can also effectively remove broad leaved weed, increased and killed careless wide spectrum, low toxicity, low-residual, easy to operate, save manpower, financial resources, reduced pollution, alleviated peasant burden environment.
The invention will be further described below in conjunction with embodiment.
Embodiment 1
Haloxyfop-r-methyl 30kg
Restrain wealthy happy 15kg
