How do I prevent the burn marks on leaves after spraying pesticide? I usually spray them at night when there is no sun and water them early in the morning before the sunrises.
However there are still burnt marks on the leaves. Does this harm the plants?

If done correctly, spraying should not cause damage to foliage, although in some cases there may be a slight residue on the leaves. Some plants are very sensitive to chemicals and may be harmed by using either the wrong spray or by incorrect application procedures. Be sure that the spray you are using is labeled for use on that particular plant and that you are following the instructions exactly in terms of application rate, dilution, any temperature restrictions, and any compatibility restrictions with regard to other sprays, and so on. It is also a good idea as a general precaution to test spray a few leaves, and wait a few days to make sure there are no adverse effects.
