Rationale, Approach and Adoption of Integrated Weed Management,. The practice of integrated pest management (IPM) is old in its use of cultural strategies or other control methods that served as the basis for pest control before the advent of pesticides. However, the current focus of IPM for weeds has been expanded to include weed biology, bio-economics, modeli

In the late 1880’s, soap was used with kerosene to destroy insect eggs, and later to increase insecticide activity of arsenic (Gillette, 1890). Fish and whale oil were also commonly used adjuvants. In 1942, surfactant enhancement was repor
