The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI - also called the active substance). Pesticide products very rarely consist of the pure active ingredient.
This is a list of fungicides. These are chemical compounds which have been registered as agricultural fungicides . The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [ 1 ]
It is currently applied in a variety of crops: fruit, vegetables, ornamental trees and shrubs and on lawns. It is a contact fungicide that inhibits the germination of fungal spores and it blocks the growth of the fungal mycelium. It has been marketed under the brand name "Rovral" and "Chipco green" (both brands of Bayer CropScience). This ...
The term applies to various pesticides such as insecticide, fungicide, herbicide and nematocide. [3] The definition of residue of pesticide according to the world health organisation (WHO) is:- Any specified substances in or on food, agricultural commodities or animal feed resulting from the use of a pesticide. The term includes any derivatives ...
The fungicides are applied at the end of the harvest and chlorothalonil has been shown in experiments to reduce purple spot by 99% and increase yields by 36%. [33] This increase in yield as a result of purple spot control has been shown to translate into a net return of $200–400 per acre for asparagus growers .
The word pesticide derives from the Latin pestis (plague) and caedere (kill). [5]The Food and Agriculture Organization (FAO) has defined pesticide as: . any substance or mixture of substances intended for preventing, destroying, or controlling any pest, including vectors of human or animal disease, unwanted species of plants or animals, causing harm during or otherwise interfering with the ...
Benomyl (also marketed as Benlate) is a fungicide introduced in 1968 by DuPont.It is a systemic benzimidazole fungicide that is selectively toxic to microorganisms and invertebrates (especially earthworms), but relatively nontoxic toward mammals.
These systemic fungicides were very effective at first. Because there is only one target site, benzimidazole resistance – fungicide resistance to this class – quickly became a serious problem. When they were the only fungicides used, pathogens became resistant after two to four seasons; when mixed with other fungicides, resistance developed ...
