Is it dangerous to put bug killer on green bean and tomato plants?

It can kill more insects than you need to. It can be sprayed or dusted on the leaves to keep beetles and grasshoppers from eating them but overuse will kill the leaves. It can be used on the ground and on the stalks of the plants to kill pill bugs and cutworms but this will also kill the worms and possibly the bacteria that the plant needs in the soil. You should not use any poisons when the plant has blooms on it as this will kill the pollenators that the plant needs to propagate. For some pests, its best to just pick them off by hand and kill them, such as catepillars and hookworms, also known as the tobacco worm. Most poisons that are used like malathion and sevin dust are water soluable and can be washed off of the beans or tomatoes with plain cold water.
