What is the difference between contact and systemic poisons?

Many pesticides are 'contact' pesticides. This means to be effective they must be absorbed through the external body surface of the insect. Systemic pesticides can be moved (trans-located) from the site of application to another site within the plant where they retain a longer residual protection against insects.

In this regard, what is a systemic insecticide?

Systemic pesticides are chemicals that are actually absorbed by a plant when applied to seeds, soil, or leaves. The chemicals then circulate through the plant's tissues, killing the insects that feed on them. Unlike with traditional insecticides, you can't wash or peel off systemic pesticide residues.

Additionally, what is systemic and non systemic pesticides? A non-systemic pesticide is a topical pesticide that can easily be washed off of a plant before consumption. Unlike systemic products, non-systemic pesticides can easily be flushed or drained from the plant's root zone prior to harvest, leaving little to no residues behind.

Also to know, what is difference between systemic and contact fungicide?

Contact fungicides are not taken up into the plant tissue and protect only the plant where the spray is deposited. Systemic fungicides are taken up and redistributed through the xylem vessels. Few fungicides move to all parts of a plant.
