This guidance is part of a holistic, proactive approach to slow the development and spread of herbicide-resistant weeds and to prolong the useful lifespan of herbicides and related technology. A herbicide is sprayed on a field of herbicide-tolerant crops to manage the weeds, but not hurt the crop.

How can humans break out of the pesticide treadmill? An early planting of peanuts, for example, can help avoid some fungal leaf spot problems which spread rapidly in warm, wet weather. Worldwide, more than 600 species of pests have developed some level of pesticide resistance. Microevolution: Definition, Examples, Quiz | Biology Dictionary Chapter 22 ~ Pesticides - Environmental Science Adopt all non-chemical techniques known to control or suppress pest populations, including biological sprays such as Bts, resistant varieties, within-eld refuges (untreated areas) and crop rotation. The composition of a closed system cannot change. Selection for resistance can occur if a small proportion of the insect population is able to survive treatment with insecticide. Bruce E.
