Spirotetramat is active against piercing-sucking insects, such as aphids, mites, and white flies, by acting as an ACC inhibitor, interrupting lipid biosynthesis in the insects, and is in IRAC group 23. [2] It is a systemic insecticide that penetrates plant leaves when sprayed on.
This is a list of insecticides. These are chemical compounds which have been registered as insecticides. Biological insecticides are not included.
The cutworm larva of the large yellow underwing (Noctua pronuba) Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm.
Chewing insects, such as caterpillars, eat whole pieces of leaf. Sucking insects use feeding tubes to feed from phloem (e.g. aphids, leafhoppers, scales and whiteflies), or to suck cell contents (e.g. thrips and mites). An insecticide is more effective if it is in the compartment the insect feeds from.
Neonicotinoids are water-soluble, so when the seed sprouts and grows, the developing plant absorbs the pesticide into its tissues as it takes in water. [9] Neonicotinoids can also be applied to the soil directly. [10] Once absorbed, neonicotinoids become present throughout the plant, including in its leaves, flowers, nectar, and pollen. [8]
It works by interfering with the transmission of nerve impulses in insects by binding irreversibly to specific insect nicotinic acetylcholine receptors. [28] It is in IRAC group 4A. As a systemic pesticide, imidacloprid translocates or moves easily in the xylem of plants from the soil into the leaves, fruit, pollen, and nectar of a plant ...
Insecticidal soap is used to control many plant insect pests. Soap has been used for more than 200 years as an insect control. [1] Because insecticidal soap works on direct contact with pests via the disruption of cell membranes when the insect is penetrated with fatty acids, the insect's cells leak their contents causing the insect to dehydrate and die.
