An insecticide destroys, suppress, stupefy, inhibit the feeding of, or prevent infestations or attacks by, an insect and the mode of actions that they work will either be by contact or systemic.

This means to be effective they must be absorbed through the external body surface of the insect. While both fungicide groups are systemic, they break the disease cycle at different points and thus differ in their role in protection of plants from infection. Group Name (Abbreviation) 1.

However, systemics take time to move up to the new shoots and control doesn’t happen until the toxic material is present where the insects or mites are feeding.
