What is the mechanism of action of the herbicide clomazone?

The mechanism of action of clomazone is that after the plant absorbs the herbicide, it can inhibit the synthesis of diterpene compounds in sensitive plants, block the biosynthesis of carotene and chlorophyll, causing the leaves to lose green color and turn white, so that the weeds die within a short period;even if seeds that absorb the herbicide can germinate and emerge from the soil, because they have no pigment, they will die within a short period. At present, it is mainly used to control annual grass weeds and broadleaf weeds.

What are the characteristics of clomazone?

1. Broad weed-killing spectrum and high activity. Clomazone can be used in soybean, rice, rapeseed, cotton, cassava, sugarcane and tobacco fields to control annual grass weeds and broadleaf weeds such as barnyardgrass, foxtail, crabgrass, goosegrass, purslane, lambsquarters, dayflower, black nightshade, cocklebur and ragweed. It also has a relatively strong inhibitory effect on thistle, cirsium, sowthistle and horsetail. At present, clomazone is considered one of the better herbicides for controlling the “three weeds” (orchid weed, sowthistle and thistle).

2. Long residual effect period. Generally, with one application, the efficacy can last through the entire growth period of the crop, and it can also exert good efficacy under drought and low-temperature conditions.

3. The application timing is relatively flexible. It can be used for pre-emergence application and pre-planting closed treatment, and can also be used for post-emergence stem and leaf treatment.

4. Low toxicity. It is very safe for crops, humans, livestock and aquatic organisms, and is environmentally friendly.

5. Strong compatibility. There are many herbicide varieties that can be mixed with it, so there are numerous compound products, which are convenient to use and highly effective.

The above is the relevant introduction to the mechanism of action of clomazone, and I hope it is helpful to everyone.
