1, dispensing with the well water. Well water contains calcium, magnesium and other minerals more easily from them and the
liquid chemical reaction precipitate, thus reducing efficacy.
Second, water dispensers. Wastewater containing impurities, will plug the dispensing nozzle, but also undermine the
stability of liquid and reduce efficacy.
Third, wind and rain days and high temperature spraying. Pesticide spraying will wind drift; wet spraying, rain washed
liquid was reduced efficacy; high temperature spraying, high incidence of crop injury and poisoning. Therefore, the best
application time is: 8:00 - 11, the 4 pm - 6 pm. Fine weather, wind spraying.
Fourth, the abuse of pesticides. Should be based on crops, prevention and control of pharmaceutical properties of objects
and the corresponding differences in pesticide use, make the right remedy, but also avoid the blind application rate
increased, resulting in enhanced pest resistance reduces the control effect, but also prone to phytotoxicity.
5, flower spraying. Spraying of crops and fruit trees in the flowering stage, prone to phytotoxicity.
6, taken before the spraying. Since pesticide residues in crops and produce, if taken prior to spraying, residues cause
food poisoning.
7, a drug 连用. Long-term use of a pesticide or a dosage form, most likely resistant to pests, reduce the control
efficacy, it should alternate medication.
