Definitions

  • Weed control is essential in the cultivation of important agricultural crops such as corn, peanuts and cotton, and in the cultivation of many horticultural species. Also, the presence of weeds on non-cropped areas can be a fire hazard, or can result in undesirable drifting of sand or snow, or can cause discomfort to persons with allergies. Control of weeds is particularly beneficial when it permits the selective control of such plants without concurrent injury to desirable crops or vegetation.
  • the problems associated with effective control of undesired plants in varied agricultural and horticultural applications are significantly different.
  • the herbicide chosen should be selective in its activity. It should kill weeds and other unwanted plants, and be harmless to the food crop plant growing or to be grown in the treated area.
  • herbicides are usually classified as selective or non-selective pre-emergents or post-emergents.
  • the most effective pre-emergence herbicide is one which is selective in its nature. If the designated compound can kill the seed and germinated seedlings of undesirable plants without harm to the seed and germinated seedlings of the crop, there will not be any problem of overpenetration of the soil by the herbicide.
  • Post-emergence herbicides are applied after the crop and weeds have attained substantial height. In general, if a compound is found to have post-emergence activity it will not be selective. As a rule, herbicidally active compounds are not selective in their action on plant life.
  • U.S. 5,022,917 discloses an extensive listing of herbicides that are effective through contact, and those that are taken up from the soil by root systems.
  • the recited herbicides include defoliants, desiccants, eradicants, systemics and selective herbicides, and related plant growth regulants.
