Answer:
weeds are unwanted plants that grow along with crop plants and compete with them for water, nutrients, space and light, thus they effect growth of crop plants. Some of the weeds are poisonous for animals and human beings and they interfere even in harvesting of crop plants. Weedicides are chemical that are sprayed in the fields to kill the weeds, they do not damage the crops. Weedicides are diluted with water and are sprayed in the field by sprayer to kill the weeds.Proper use of manure as a fertilizer minimizes nutrient pollution to water resources and helps build healthy soils. Manure nutrients can also be used to grow worms, insect larvae, algae, or other living organisms
