How to use plant regulators well? Correct usage is the key
What should be noted when using plant growth regulators in vegetable fields? How should they be applied? When growing vegetables and using plant growth regulators, note the following points: 1. Pay attention to the scope of application. PCPA (4-CPA) can be fully and effectively applied for flower dipping on solanaceous vegetables, but if sprayed on cucumber, green pepper or kidney bean, it will cause young tender tissues and leaves...
How to use plant regulators well? Please explainPlant growth regulators are regulatory substances within organisms. When using them, first, note that they cannot replace fertilizer - that is, they cannot replace fertilizer, water or other agricultural measures. Even growth-promoting regulators can only play their role under conditions of sufficient fertilizer and water. Second, do not change the concentration carelessly. Crops have relatively strict requirements for the concentration of plant growth regulators. If the concentration is too high, it will cause leaves to thicken and become brittle, deformed leaves to dry up and fall off, and even the whole plant to die; if the concentration is too low, it will not achieve the desired effect. Third, pay attention to timely use. The use of plant growth regulators should be based on their type, climatic conditions, duration of efficacy and cultivation needs, and the best timing should be selected to avoid unnecessary input. Fourth, do not mix them arbitrarily. Whether several plant growth regulators are mixed or mixed with other pesticides and fertilizers, the feasibility must be decided on the basis of fully understanding the enhancing or antagonistic effects between the mixed pesticides. Do not mix them arbitrarily.
