How to prevent phytotoxicity from plant growth regulators in cotton
How can cotton avoid phytotoxicity from plant growth regulators? Please advise on phytotoxicity from plant growth regulators and its symptoms: for the commonly used chlormequat, if the application concentration is too high or the dosage is too large, it will inhibit cotton plant growth, making the plants too short, causing buds and bolls to drop easily, and even deforming the bolls. When mepiquat chloride is sprayed in excess, it will inhibit...
