Crop Herbicides

Weed management is important in crops as uncontrolled weeds start to compete for water and nutrients, affecting plant vigor and crop quality. It is preferable to use selective herbicides in crops, as non-selective herbicides are likely to damage the non-target plants as well. A number of herbicides are effective for weed control in crops.
  1. Types

    • Herbicides that help to control crop weeds include bensulide and metolachlor. The chemicals are sold under different trade names.

    Description

    • Products containing bensulide are preemergence herbicides that retard the germination of weed seeds. The organophosphate herbicide is selective in nature and sold in the form of emulsifiable liquid. Metolachlor herbicides are also for preemergence weed control. The general-use chemical works by damaging protein synthesis processes in plants.

    Crops

    • Bensulide effectively controls a number of broadleaf weeds and annual grasses like crabgrass and bluegrass in cucumbers, peppers, carrots, cotton and melons. The herbicide may also be used in turfgrass and also in combination with other chemicals for added efficacy. Metolachlor also manages annual grasses and some broadleaf weeds in peanuts, soybeans, corn, potatoes, cotton, grain sorghum and pod crops.
