In the young fruit stage, the cell tissue is relatively young, and any bad stimulation from the outside will cause damage to the epidermal cells of the fruit, resulting in poor fruit quality and quality in the future. Therefore, safe medication during the young fruit period is essential.
First of all, the dosage form should be selected mainly from water-dispersible granules, water emulsions and microemulsions. Water-dispersible granules are evolved on the basis of a wettable powder, an aqueous suspension of a new dosage form, in addition to maintaining the good efficacy of the original drug, but also has little pollution, good solubility, ability and affinity with water, suspended Good performance and other characteristics. Therefore, it is especially safe for young fruits.
Secondly, an agent that uses an alcohol as a solvent and a vegetable oil as an auxiliary agent should be selected to avoid the use of an agent or a solvent such as benzene or xylene or diesel.
Once again, when mixing the drugs, try to reduce the number of samples. Do not increase the number of use at random. Try to prevent a disease from being treated with a drug.
Finally, the pressure should be sufficient when spraying, the atomization effect should be good, and it should be far away from the fruit, so that the droplets drifted to avoid mechanical damage to the fruit surface.
