isoxazole herbicides | isoxazolone (isoxaflutole, bainongsi) is an isoxazole herbicide, which is a selective systemic pretreatment herbicide, which mainly works through the absorption and conduction of young roots of weeds. After sensitive plants absorb the drug, they indirectly affect the biosynthesis of carotenoids by inhibiting 4-p-hydroxyphenylacetonate dioxygenase (carotenoids play an important role in the process of photosynthesis, and it can collect Light energy also has the function of protecting light from damaging chlorophyll), which causes sensitive plants to lose green, whiten and wither after being damaged. The duration of isoxazolone is moderate, and the residual duration is 4 months in general. isoxazolone is mainly used in dry crops such as corn and sugarcane to control Abutilon, Chenopodium, Kochia, Salsola, Solanum nigrum, Amaranth, Polygonum willow, Bidens bipinnata, Portulaca oleracea, Trichens, Elsholtzia, Xanthium, Amaranth, Amaranth, Amaranthus aqua, Polygonum sorbifolia, Monozoa and other annual broad-leaved weeds, it also has a good control effect on some annual gramineous weeds such as crabgrass, barnyard grass, ox tendon grass, thousand gold, seisegrass and seisegrass. isoxazolone has no internal absorption conductivity and is used to prevent and remove broad-leaved weeds. When the amount is large, it will burn wheat leaves and die quickly. However, weeding is easy to relapse, and it has poor effect on chow, large nest vegetables, etc. It can be used in combination with tribenuron, dimethyltetrachloride, etc, it is best used in weed 3-4 leaf stage. isoxazolidone is selective to corn, but under the soil conditions of excessive dosage, alkaline soil, sandy soil and low organic matter content, corn is easy to produce medicinal damage. Some corn varieties are also prone to drug damage, and corn produces yellowing and albinism. |
