Pesticides do have the potential to harm plants. First, the toxic ingredients contained in pesticides can cause plant and animal discomfort and even illness. In addition, if pesticides are accidentally sprayed into water, plants may die by absorbing water. However, this does not mean that all plants cannot use pesticides. For example, some plants such as plum, cherry, peach, apricot, elm and other ornamental plants will have obvious phytotoxicity when using certain pesticides, and other kinds of pesticides should be used instead. In general, the use of pesticides requires caution. The decision on whether to use them, as well as the timing and method of use, should be based on the type of plant and the nature of the pesticide.
