Weedicides
Weeds are unwanted plants growing among wanted crops and compete with crop plants for sunlight, nutrients, water etc. They grow in the fields where they compete with crops for water, soil nutrients, light and space and thus reduce crop yields.
The controlling of weeds in the growing crops with weedicides increases their yields and ensures the efficient use of irrigation, fertilizers and plant-protection measures, such as the spraying of insecticides and fungicides.
Both the nature of the weeds and that of the crops which they infest, influence the action of the weedicides. For example, the same types of weeds occur in maize and cotton which are kharif crops. 2,4-D can be used for killing the weeds in maize, but this weedicide should never be used on cotton which is highly sensitive to it.
To manage the weeds in direct seeded rice, four weedicides were tested and compared their efficacy with handweeding. Among the weedicides.
Nominee 100SC (bispyribac sodium) and Sunstar Gold 60WG (Ethoxy sulfuron) proved as the best weedicides with 90.5 and 87.19% weed control respectively.
Weedicides are the chemicals which are sprayed over field to get rid of weeds. They will not show any effect on crop plants. Two popularly used weedicides are 2,4-D Ethyl ester, Neem extract, Glyphosate etc.
