Any insect population may contain individuals naturally resistant to Lorsban 4E and other Group 1B insecticides. The resistant individuals may dominate the insect population if this group of insecticides is used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action but are specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance management strategies should be followed.
- Uniform crop coverage is essential.
- Use a boom configuration that provides optimum coverage.
- Use higher rates where infestations are heavy or foliage is dense.
