Weeding composition containing trifluoromethyl pyridazinol compound, and application of weeding composition

Abstract

The invention belongs to the field of pesticides, and particularly relates to a weeding composition containing a trifluoromethyl pyridazinol compound, and application of the weeding composition. The weeding composition comprises an effective weeding amount of an active component A and an effective weeding amount of an effective component B, wherein the active component A is selected from one or more than two of compounds represented by a general formula I, X represents unsubstituted or substituted aryl and heteroaryl, and the active component B is selected from one or more of the following compounds and salts / esters thereof: an HPPD inhibitor, a PDS inhibitor, a DOXP inhibitor, an ALS inhibitor, an ACCase inhibitor, a PPO inhibitor, a PSII inhibitor, a microtubule assembly inhibitor and the like. The composition can be used for effectively preventing and removing weeds such as chenopodium album l, green setaria viridis, lamium amplexicaule l, wild oats, hemistepta lyrata bunge, eleusine indica, geranium wilfordii, lithospermum arvense, broomcorn millet, amaranthus retroflexus, barnyard grass and the like in crop fields, and has the characteristics of expanding a weed control spectrum, reducing application amount, generating synergism, solving resistant weeds and the like.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition containing trifluoromethylpyridazinol compounds and applications thereof. Background technique [0002] Chemical herbicide is the most economical and effective means of controlling weeds in farmland, but long-term continuous high-dose use of a single species or single mode of action of chemical herbicides is likely to cause problems such as weed resistance and resistance evolution. Reasonable compounding or mixing of herbicide compounds has the advantages of expanding the spectrum of weeds, improving the control effect, delaying the occurrence and development of weed resistance and drug resistance, and is one of the most effective methods to solve the above problems. For example, the patent CN1543455A describes a herbicidal composition containing 3-phenoxy-4-pyridazinol derivatives, but it still needs to be developed in production with high safety, w...
