Weedicides
Weedicides are products that are sprayed over the fields to get rid of weeds. There are two types of weedicides one is pre-emergent and other is post emergent. Pre-emergent herbicides are a proactive approach to weed control by working to kill weeds before they appear. Whereas pre-emergent herbicides work by creating a chemical barrier in the top layer of soil that coats seeds and prevents them from growing roots and shoots. Weedicides will be in the form of dry granules and liquid and they can be watered into the top soil or can be sprayed on the weeds. Weedicides will be available both in the form of chemical & organic products. Most of the chemical weedicides would result in air, water and soil pollution. Chemical weedicide have long residual life in the soil and on plants than organic weedicides. Organic weedicides are lesser effective but are safe to environment & human. The demand for weedicides in general and organic weedicides in particular is increasing by the farmers mainly due to labour issues at the farm level.
