How to remedy herbicide damage in rice?
What should you do if herbicide application to rice causes phytotoxicity? To increase the weed-killing effect and broaden the herbicidal spectrum, most compound herbicides contain bensulfuron-methyl, pyrazosulfuron-ethyl, acetochlor and the like. If farmers do not know how to use them, phytotoxicity is easily caused. 1. Judging phytotoxicity. Rice may show symptoms similar to herbicide phytotoxicity because of root suffocation, nutrient deficiency, or pests and diseases...

Precautions for Using Plant Growth Regulators on Fruit Trees
What should be noted when applying plant growth regulators to fruit trees? Plant growth regulators are synthetic organic compounds that promote, inhibit or otherwise alter a specific growth process in plants. Although they are trace substances, they can produce noticeable effects. But improper use often backfires, while rational use...

Methods for applying herbicides to wheat to prevent freeze-related herbicide injury
What herbicide is best for corn planting? Corn plants that preferably do not suffer herbicide injury are relatively sensitive to herbicides, so they should be chosen reasonably to avoid herbicide injury. For soil treatment, 40% atrazine-acetochlor aqueous suspension emulsion has high herbicidal activity, a long application period, and is safe for corn and subsequent crops. Before emergence after sowing or after emergence when weeds...
