Weed Control and Herbicides - Herbicides are being developed which will be environmentally safe. To allow the use of these herbicides for crop protection programme, genetically engineered herbicide resistant plants have been produced in a number of crops, which should eventually allow the use of environmentally safer herbicides. These plants arc being field tested. Similarly, genetically engineered insect resistant plants have also been successfully produced in some crops thus raising the hope for reduced use of insecticides in future.
