Agricultural field weedicide

Abstract

The invention belongs to the field of agricultural weedicide and particularly relates to an agricultural field compound weedicide. The agricultural field compound weedicide comprises the effective constituents of flumetsulam and pinoxaden which are compounded, wherein the weight ratio of the flumetsulam to the pinoxaden is 1 to 0.1-20, preferably 1 to 2-8. The prepared compound weedicide is wide in phytocidal range, and has a better effect in preventing gramineous weeds, broad leaf weeds and sedge weeds in the field, in particular for difficultly prevented and killed worst weeds. The compound weedicide has a remarkable synergistic effect, which is not simple superposition of the activities of the constituents. The compound weedicide has a strong prevention and control effect and is long in effect duration time and low in resistance risk. The usage amount of the effective constituents in the field is reduced, the production and use costs are lowered, and weedicide residues and environmental pollution are reduced. The compound weedicide comprises the effective constituents with different acting mechanisms, is favorable for overcoming and delaying the weedicide resistance of pathogenic bacteria, and is safe to crops.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, in particular to an agricultural field compound herbicide. Background technique [0002] Herbicide varieties containing a single active component often have different degrees of defects in the control of weeds in agricultural fields. For example, weeds are prone to resistance after continuous application, the herbicide spectrum is narrow, and frequent applications will aggravate environmental pollution. One way to control agriculturally resistant weeds is to introduce new ingredients that are not cross-resistant with existing varieties. However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of weed resistance. Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of weed resistance

Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

[0003] Pinoxaden is a new phenylpyrazoline herbicide, the mechanism of action is acetyl coenzyme A carboxylase (ACC) inhibitor, which causes fatty acid synthesis to be blocked, cell growth and division to stop, cell membrane lipid-containing structure to be destroyed, resulting in miscellaneous grass death
