Abstract

The invention relates to a tembotrione-containing weeding composition which is characterized by comprising two effective constituents namely tembotrione (A) and (B), wherein (B) is at least one selected from metolachlor and flufenacet; the weight part ratio of A to B is (56:1)-(1:63), and (30:5)-(5:40) preferably. In the composition, the total weight part of A and B accounts for 1-80% of that of the composition, and 5-45% preferably. Pesticide preparation forms such as wettable powder, a suspending agent, missible oil, a microemulsion, an emulsion in water, a granular formulation and a water dispersible granule can be prepared from the tembotrione-containing weeding composition. The tembotrione-containing weeding composition enlarges the weeding spectrum, overcomes the defect that metolachlor and flufenacet are inefficient in preventing broad-leaf weeds, greatly increases the prevention and kill-off rate, retards occurrence of resistance of weeds, reduces the repeated application times of a pesticide, and decreases the application amount of the pesticide and agricultural cost.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing tembotrione. Background technique [0002] Triketone is a new type of triketone herbicide, which is also an HPPD inhibitor, and is mainly used for weeding in corn fields. Its chemical structural formula is: [0003] . [0004] Metolachlor is an amide selective herbicide with the chemical name 2-chloro-2',6'-diethyl-N-(2-propoxyethyl)acetanilide. It is mainly transmitted upward through the absorption of the young shoots of plants, namely monocots and coleoptiles, and the hypocotyls of dicotyledonous plants. After emergence, it mainly relies on root absorption and upward conduction, inhibiting protein synthesis and causing death. When the soil moisture is good, the weeds will be killed at the budding stage; if the soil moisture is low, the soil moisture will increase with the rainfall after the weeds emerge, and the weeds will...
