Weeds in cotton fields compete with cotton for light, water resources, nitrogen, phosphorus and potassium nutrients and growth space all year round, seriously restricting the vegetative and reproductive growth of cotton. Studies have shown that it can cause a 14% to 16% reduction in cotton production, seriously restricting the high-quality and efficient production of cotton. When weed damage is serious, it can even cause a 60% reduction in cotton production.

Common weeds in cotton fields include field bindweed, nightshade, amaranth, gray-green quinoa, quinoa, concave-headed amaranth, chicory, purslane, white amaranth, wild watermelon seedlings, thistles, etc.

Cotton herbicides are divided into soil sealing treatment and stem and leaf treatment.

Soil sealing is to apply herbicides into the soil after sowing before the seedlings emerge in the field. When the seeds, sprouts and seedlings of the weeds come into contact with the agent, they will be killed. It is one of the key measures to prevent and control weeds.

The stem and leaf treatment agent is diluted with a certain proportion of clean water and sprayed directly on the weed leaves, killing the weeds by contacting their leaves and stems.
