【Dispensing with well water】Sanzheng Organic


Well water contains a lot of minerals such as calcium and magnesium, which easily react with the chemical liquid to form precipitates, thereby reducing the efficacy of the medicine.


【Sewage Dispensing】


Sewage contains many impurities, the dispensing will block the nozzle, it will also destroy the stability of the liquid and reduce the efficacy.


【Apply in wind, rain and high temperature】


Wind spraying will cause the pesticides to float away; when spraying on rainy days, the liquid will be washed away by the rain to reduce the efficacy; spraying under high temperature will cause phytotoxicity and poisoning. Therefore, the best application time is: 8 am to 11 am, and 4 pm to 6 pm. The weather was fine and the breeze applied the medicine.

三征有機(jī)

  

【Abusing pesticides】


Corresponding pesticides should be adopted according to the different types of crops, control objects and chemical properties, so as to prescribe the right medicine. At the same time, avoid blindly increasing the amount of pesticides, which will increase the resistance of pests and reduce the control effect, and it is easy to produce pesticide damage.


【Flowering spray】


Agricultural crops and fruit trees are prone to phytotoxicity when they are applied during the flowering period.


【One drug in combination】


Long-term use of one or one formulation of pesticides is most likely to make pests resistant and reduce the control effect, so the pesticides should be used alternately.
