Adhesive agent can improve the efficacy of waxy vegetables
There are a layer of white powdery waxy vegetables on the leaves, such as green onions, cauliflowers, and cabbages. When pests and diseases are controlled, the surface of the leaves is often covered with wax and the desired effect is not achieved. Therefore, a small amount of adhesive should be added to the vegetable with a waxy layer when spraying. The specific method is as follows: Take 0.1% of the neutral detergent powder as the adhesive agent, dissolve it thoroughly with warm water and set aside. When dispensing the pharmaceutical solution, first pour a reasonable dose of the drug solution into the cartridge. When adding water to one-third of the solution, pour the adhesive solution, then add enough water and mix well. It should be noted that lime, dexamethasone, sulphur sulphide, thiram, carbamide, thiophanate, carbendazim, dibromophosphorus, etc. will lose their effect when mixed with detergent, and detergent can not be used as an adhesive. Pesticides that can be mixed with washing powder include chlorothalonil, Bordeaux and pyrethroid pesticides.
