Problems solved by technology

[0003] High-efficiency grass-covering energy, wide application range, wide herbicidal spectrum, long-lasting effect, less dosage per mu, high activity, can be used in combination with a variety of herbicides, expands the herbicide spectrum, improves drug efficacy, and is easy to use. It can be used for pre-emergence treatment and post-emergence treatment, with low toxicity, but it is only effective against gramineous weeds, not broad-leaved weeds

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 [0001] The invention relates to an onion field herbicide composition and a herbicide method. Background technique [0002] There are many types of weeds in onion fields, early occurrence, large amount of occurrence, and long damage period, so it is difficult to prevent and control. When using chemical weed control, its application type, application period and dosage must be very precise, otherwise it will cause phytotoxicity. [0003] High-efficiency grass-covering energy, wide application range, wide herbicidal spectrum, long-lasting effect, less dosage per mu, high activity, can be used in combination with various herbicides, expands the herbicide spectrum, improves drug efficacy, and is easy to use. It can be used for pre-emergence treatment and post-emergence treatment, and has low toxicity, but it is only effective against gramineous weeds and has no effect on broad-leaved weeds. Contents of the invention [0004] The object of the present invention ...
