Which form of pest management targets plant-eating larvae specifically?

In this context, the focus of the question is on pest management methods that specifically target plant-eating larvae, which are generally the immature stage of certain insects. Insecticides are designed to control various stages of insects, including eggs, larvae, nymphs, and adults. When dealing with plant-eating larvae, which can cause significant damage to crops and plants, insecticides are the most effective choice as they are formulated to disrupt the growth or life cycle of insects.

In contrast, the other options serve different purposes and target different types of organisms. Fungicides are used to control fungal diseases and are not effective against insect larvae. Nematicides target nematodes, which are parasitic worms, and would not help with insect larvae. Piscicides are designed to control fish populations and are irrelevant in the context of managing insect pests on plants.

By selecting insecticides, growers can directly address the issue posed by the larvae, protecting their plants and achieving effective pest management.
