Abstract

The invention relates to an ultralow-volume liquor containing amicarbazone. The ultralow-volume liquor consists of an active ingredient, an auxiliary agent and a dissolvent, wherein the active ingredient is amicarbazone, or complex combination of amicarbazone and an active ingredient II, and the active ingredient II is any one of nicosulfuron, metolachlor and acetochlor. An airplane, a tractor or an ultralow-volume atomizing machine is adopted for carrying out ultralow-volume atomization for preventing and controlling weeds in corn fields and sugarcane fields so as to solve the problems that in the existing weeding work in corn fields and sugarcane fields, the work of water fetching, dispensing and water loading are heavy and much physical labor is required to be wasted; and the ultralow-volume liquor containing amicarbazone has the advantages of simple production technology, high work efficiency and low weeding cost, and medicines are saved.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to an ultra-low-capacity liquid containing amfentrazone. Background technique [0002] At present, my country lacks excellent herbicides for sugarcane fields, and due to the extensive use of atrazine in corn fields, groundwater and surface water in some areas have been polluted, and weed resistance has grown rapidly. The period is longer, and the increase of the dosage makes the residual amount in the soil easy to damage the sensitive crops. As an excellent photosynthesis inhibitor, amfentrazone will produce good economic and social benefits in its production and use. At the same time, reasonable compounding can make the active ingredients produce synergistic effects, which can improve the control effect and reduce the amount of pesticides. Save costs, delay the emergence of weed resistance, and thus reduce or even avoid the pollution of food and the environment by pesticides. ...
