Matters needing attention in pest control

(l) spraying should be carried out in the morning or evening when the temperature is relatively low.

(2) the concentration of diluted solution should be in accordance with the operating instructions. If the concentration is too high, it will produce drug damage; if the concentration is too low, the effect is not good. Also pay attention to the expiration date.

(3) Pesticide spraying should be comprehensive and uniform, and the leaf surface, leaf back, basin edge and ground should be sprayed.

(4) if the two drugs are mixed, read the instructions first, so as to avoid losing the efficacy or harming the orchid seedlings due to chemical reactions.

(5) do not use one pesticide for a long time, but use a variety of pesticides alternately so as not to produce drug resistance and affect the effect of control.

(6) pesticides are mostly toxic, and personal safety should be paid attention to when using them.
