Impact to the crop
Weeds are considered as one of the limiting factors in crop production as it:
√ Compete with crops: Nutrients, Water, Space, Sunlight (Yield reduction)
√ Increase cost of cultivation
√ Reduce crop quality and contaminate produce
√ Interfere with harvesting
√ Serve as an alternate host for pests & diseases
√ Allelopathy; production of chemicals toxic to crop plants, animals, or humans
How to control
√ Mechanical control thru cultivation, uprooting and burying of weeds using mechanical tools
√ Physical control thru hand weeding
√ Cultural methods by thorough land preparation, appropriate plant spacing and good water management
√ Chemical control by the use of herbicides
