Pesticide Resistance & safe Use of agrochemicals

Through evolution plants and animals have developed defensive mechanisms, including chemical repellents and toxins, against attacking organisms. Pesticide resistance, is a genetically based phenomenon and occurs when a pesticide is used on a population containing some individuals genetically predisposed to be resistant to that pesticide. Repeated applications and higher treatment rates will kill increasing numbers of the pest but resistant survivors will pass the resistance genes to the next generation. Unless a different treatment regime is used the population will contain increasing numbers of resistant pests and where reproductive rates are high, e.g. in insects, the entire population will quickly become resistant.

Use of Different pesticide

Once a pest has developed resistance to a particular pesticide it is necessary to have other means of controlling it. One method is to use a different pesticide, especially one in a different chemical class that has a different mode of action against the pest. Care must be taken, however, that cross-resistance, i.e. resistance to several classes of pesticides, is not introduced into the population. In this article we give you a list of chemical control to products of three major agrochemical companies in Kenya.
