Method for controlling herbicide-resistant weed

A method for controlling weeds in a cultivation area of soybean, which includes applying trifludimoxazin and saflufenacil to growing weeds in the cultivation area of soybean, wherein an application rate of trifludimoxazin is approximately 10 to approximately 12.5 g/ha and an application rate of saflufenacil is approximately 20 to approximately 25 g/ha.

Method of controlling weeds

The present invention provides a method for controlling weeds comprising a step of treating a cultivation area of crops with ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-3-yl)phenoxy]-2-pyridyloxy]acetate or flumioxazin before, simultaneously with, and/or after sowing crop seeds, which has an excellent efficacy for controlling weeds in a cultivation area of crops. The present invention also provides the above-mentioned method wherein the crops are the transgenic plant body or seeds that are tolerant to the protoporphyrinogen oxidase (PPO) inhibitors; and further provides the above-mentioned method wherein the crops are the transgenic plant body or seeds having any one of a polypeptide sequence selected from the group consisting of SEQ ID Nos. 1-32 described in the Description or a polypeptide sequence having at least 85% sequence identity to any one of SEQ ID Nos. 1-32.

Method for controlling harmful organisms in crops

The present invention can provide a method exerting an excellent control effect in the control of glyphosate-resistant weeds. The method includes the step of applying to 200 g per 10000 mof trifludimoxazin to the glyphosate-resistant weed or a habitat of the glyphosate-resistant weed.

A method of controlling a weed including applying trifludimoxazin and glyphosate potassium salt to the weed or a habitat of the weed, wherein an application rate of trifludimoxazin is approximately 6.25 to 12.5 g per 10000 mand an application rate of glyphosate potassium salt is approximately 1540 g per 10000 m.
