Benzoxaborole Compounds for Low-Rate Herbicidal Control

The patent applies parameter changes by modifying the chemical structure of herbicidal compounds to include specific benzoxaborole core structures with defined substituent patterns (R1-R7 groups). This structural parameter change results in compounds that achieve effective herbicidal action at lower application rates compared to conventional herbicides, directly resolving the contradiction between effectiveness and quantity required.

The patent applies local quality by introducing specific substituent groups (R1-R7) at defined positions on the benzoxaborole core structure. These localized structural modifications create compounds with improved selectivity, allowing effective herbicidal action on unwanted vegetation while maintaining compatibility with crop plants, thus resolving the contradiction between effectiveness and crop safety.

By changing the chemical parameters of the herbicidal compounds to specific benzoxaborole structures with optimized substituent patterns, the patent enables effective weed control at reduced application rates. This parameter optimization directly addresses the contradiction between achieving sufficient herbicidal action and minimizing the quantity of chemical substance applied, thereby reducing cost and environmental impact.
