Dicamba should generally be applied during periods of active plant growth. For instance, in northern climates, spring Crabgrass applications are often timed when Forsythia is blooming, which frequently (but not always) occurs when soil temperatures are in the 50°F range. herbicide in home landscapes is 2,4-D which is used to control broadleaf weeds in the lawn. Spot and basal bark treatments can be applied when plants are dormant, but should not be done when snow or water prevent application directly to the ground. Selective herbicides control specific weed species, while leaving the desired croprelatively unharmed, while non-selective herbicides (sometimes called total weedkillers in commercial products) can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact. Nonselective or broad-spectrum herbicides are used to kill all vegetation in an area. As for using If you have a yard, you have weeds. local Cooperative Extension System office A herbicide is a chemical used to kill or inhibit plant growth. Organic Methods for Killing Weeds Safely Herbicides can also be selective and used to kill only targeted plants, for example, crabgrass killer.
