We are accustomed to weeding after the Chinese New Year. I would like to use 100ml of quinolonepentapine per acre and add 108g/L of flupirazid. Spirit 30 ml?
Clear water: Can be added.
Refined quinolonephrine is a compounding agent of quizalofop and gracilin. Grass removal is mainly used to control broad-leaved weeds. When removing the spring, attention should be paid to the application of rapeseed before convulsions to avoid phytotoxicity. Both quizalofop and high-efficiency flupirtine can be used to control grassy weeds such as aphids and bluegrass. Among them, quizalofop-methyl is suitable for controlling grassy weeds in the low-grain period below the 4-leaf stage, and it is necessary to increase the dosage after the increase of grass age, and the weeding effect is poor when the grass age is too large. In addition, the drug requires a relatively high temperature, and the herbicidal effect is significantly reduced at a temperature below 15°C. When the temperature is lower than 10°C, no herbicidal effect is obtained. Efficient flupiramridate can be used to control old grass weeds. It also has better control effect in the low temperature period, but the effect of weeding will be greatly affected when the temperature is lower than 10°C. In addition, due to long-term use, in many places including Binhai, there are a large number of Gramineae weed populations that are resistant to quizalofop-p-ethyl, high-efficiency flupirazidime, and Japanese aegis. When the temperature is large and the temperature is low, the use of quizalofop-p-ethyl and high-efficiency flupirtine have no effect on the stability of these resistant weeds.
Early-maturing pods are eared early, and it is difficult to control them with drugs after heading. Grass removal application time can not be too late. Therefore, the rapeseed field should be removed early in spring, so the temperature during the application period is usually lower. If weeds occur earlier in the field and the temperature during the spring application is relatively low, the mixture of clethodim and herbicide should be used. The clomazone herbicide has a wide spectrum of grass weed control and can control many grassy weeds in rapeseed fields. It can also prevent weeds such as quizaldoprenaline, which is resistant to quinolazine and other drugs. The drug can exert better herbicidal effect when the temperature is higher than 2°C, and the temperature requirement of the pesticide is relatively low.
