Diquat
Diquat is not only a non-selective, fast-acting herbicide, but also a plant growth regulator. It causes injury only to the parts of a plant where it is applied.
Additionally, this product is a desiccant because it allows a leaf or an entire plant to dry out quickly. It can desiccate potato vines and seed crops, so as to control flowering of sugarcane, and for industrial and aquatic weed control. Diquat is not residual. In other words, it does not leave any trace of herbicide on or in plants, soil, or water.
Usage
1. Diquat is ideal for pre-harvest desiccation of cotton, flax, alfalfa, clover, lupins, oilseed rape, poppies, soybeans, peas, beans, sunflowers, cereals, maize, rice, sugar beet, and other seed crops.
2. It is also used for the destruction of potato haulms and the stripping of hops.
3. This product is able to control annual broad-leaved weeds in vines, pome fruit, stone fruit, bush fruit, strawberries, citrus fruit, olives, hops, vegetables, ornamental plants, shrubs, and other crops.
4. Control of emergent and submerged aquatic weeds.
5. Weed control on non-crop land.
6. Weed control and tassel inhibition in sugarcane.
7. Application rates vary from 400 to 1000g/ha.
