Which type of pesticide can be taken up and distributed by the plant?

A systemic pesticide is designed to be absorbed by the plant and then distributed throughout its tissues. This means that when a systemic pesticide is applied, it moves within the plant, making it effective not only against pests that directly contact the treated parts but also against those that may feed on other areas of the plant later on. This internal distribution helps to ensure comprehensive pest control, even if the pests are chewing or sucking from parts not directly treated.

Contact pesticides, on the other hand, only affect the pests that come into direct contact with the chemical application; they do not penetrate the plant. Fungicides are primarily used to control fungal diseases and do not typically function in the same way as systemic insecticides or herbicides. Granular pesticides are formulated in a solid granule form and may either be surface treatments or can be taken up by plants, but they generally work in a different way than the systemic type, which is specifically designed for absorption and distribution throughout the plant.
