Gramoxone is a fast killing herbicide, which has contact killing effect and certain internal absorption effect.

Gramoxone is used as a quick acting, broad-spectrum, contact killing and killing herbicide. After bipyridyl cations are rapidly absorbed by plant leaves, they are reduced to bipyridyl free radicals through photosynthesis and respiration in green tissues. After self oxidation, water and oxygen in leaf tissues form hydrogen peroxide and peroxy free radicals, destroy chloroplast membrane, stop photosynthesis and chlorophyll synthesis, and promote drying. Gramoxone is used before seedling, it loses its activity in contact with soil, and has no effect on crop seedlings unearthed after spraying. No effect on brown bark, woody plant trunks are safe. Light can increase the efficacy. The cloudy day delaying medicine is effective. Gramoxone can also be used in orchards, mulberry fields, rubber plantations, tea gardens, paddy fields and wheat fields. (weeds, Cyperus, Cyperus, pomoea, Cyperus, Sturnus, bristle, cricket grass, and bamboo leaf grass) generally use 20% water agent 30~45 ml/100m² to spray 3.75 kg of water.   Gramoxone is a large variety of non selective herbicide. It can touch and kill ground weeds and dry them before crop emergence. It is used for weeding in orchards, mulberry orchards, rubber orchards, paddy fields, dry lands and no tillage plantations. Gramoxone can control various annual weeds; it has a strong killing effect on perennial weeds, but its underground stems and roots can sprout new branches; it has no effect on the brown stems and trunks that have been lignified. It is suitable for the control of weeds in orchards, mulberry gardens, rubber gardens and forest belts. It can also be used to control weeds in non-arable land, ridges and roadsides. For broad-row crops such as corn, sugarcane, soybeans and nurseries, directional spray can be used to prevent and control impurities Grass.  Gramoxone can be used as a late-stage auxiliary agent as a defoliant for machine-harvested crops. Since the crops use defoliants and do not achieve the ideal defoliation effect when the harvesting period is approaching, gramoxone can quickly kill the green tissues of the crops, make them dehydrated and dry, and will not affect the short-term stacking and storage of the harvested fruits after mechanical harvesting. For example, cotton, peppers and other crops are harvested from seed cotton and fruits with low moisture regain. When the moisture regain is high, mildew will occur when stacked in a short time.

Safety to crops: Gramoxone is a biocidal herbicide. If it is not sprayed on the green stems and leaves of the crop, the liquid will only contaminate the brown lignified bark and branches, which will not harm crops and trees. Gramoxone will lose its activity in contact with soil, and it will be removed 1-2 days before sowing, which is safe for crops.
