Nicosulfuron-atrazine mixed herbicide

Abstract

The invention relates to a nicosulfuron-atrazine mixed herbicide, which contains the following effective ingredients: 2% (weight) of nicosulfuron and 20% (weight) of atrazine. The effective ingredients and known assistants can be compounded into conventional dosage forms including powder, wettable powder, suspension emulsions, missible oil and granules. With a wide weed control spectrum, the nicosulfuron-atrazine mixed herbicide can prevent and remove weeds in corn fields, and also can kill weeds in other crop fields. With outstanding advantages in the aspects of improving the weeding effect, reducing pesticide residual activity, lowering phytotoxicity, delaying the drug resistance occurrence of weeds and community succession, lowering drug consumption, and reducing environmental pollution, the mixed herbicide also saves time, labor and money simultaneously, thus being more easily acceptable to farmers.

Description

technical field [0001] The invention relates to a herbicidal pesticide composition, especially a mixed herbicide of nicosulfuron-methyl and atrazine. Background technique [0002] Nicosulfuron is a special herbicide for post-emergence corn fields. It has significant control effect on grass weeds and some broad-leaved weeds in corn fields. It is safe for corn. High activity, good activity only on some broad-leaved weeds, its herbicidal spectrum is narrow. [0003] Atrazine is a systemic selective pre-emergence and post-emergence herbicide. It is mainly absorbed by roots and has little absorption by stems and leaves. It is suitable for corn, sorghum, sugarcane, fruit trees, nurseries, woodlands, and against cruciferous and leguminous weeds. And some perennial weeds have a certain inhibitory effect, and it is easy to be washed by rainwater to the deeper soil layer. It is also effective for some deep-rooted weeds, but it is easy to cause phytotoxicity and has a long lasting eff...
