Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations containing flumioxazin and haloxyfop-r-methyl, for preventing and treating soybean weeds.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", (1) is safe, and this not only requires toxicity low, residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of current Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of effective approach, by adjusting the proportioning of different agricultural chemicals, make the agricultural chemicals of performance complement obtain best synergistic effect.
