Dichlobenil, fluazifop, glyphosate, napropamide, oryzalin, sethoydim, simazine, and terbacil are chemicals which can be used in raspberries to kill weeds. Dichlobenil and napropamide may be applied respectively from late winter to early spring and from fall to early spring. The other six active ingredients, also called common names, mentioned above power post-emergence herbicides.

Pre-emergent and post-emergent herbicides are the types of weed killers that kill sandburs (Cenchrus spp), bunch-type, low-branching annuals and perennials of open fields and meadows and of drought-weakened turf. Pre-emergent herbicides that control crabgrass include the common names benefin, DCPA, oryzalin, oxadiazon, or simazine. Post-emergent weed killers range from the organic arsenicals DSMA or MSMA in bermudagrass lawns to imazaquin in warm-season grasses and Saint Augustine grass.

Digging up, hoeing, mulching, releasing natural enemies, solarizing and spraying are ways to get rid of goat's head weed. The hairy-leaved, yellow-petaled plant in question (Tribulus terrestris) can be controlled by manual or mechanical removal from shallow depths, mulching 3-inch (7.62-centimeter) layers, releasing weevils (Microlarinus lareynii and M. lypriformis) and spraying pre-emergent benefin, oryzalin or trifluralin and post-emergent dicamba or 2,4-D. Solarizing with weighted-down black plastic sheeting gives the area a chance to start all over with aerated soil that will support ground covers to goat's head weed's detriment.

A non-residual, target-specific herbicide is a weed killer that does not kill iris. The herbicide may be either pre-emergent or post-emergent. It must not be a weed killer that impacts all vegetation in the immediate area or that remains in the environment.

To kill weeds and not the bushs is done by using your weed killer product up to the roots of the bush. Most roots of a bush are no wider then the branches of the bush. Then you will manually need to remove the weeds around the bushs. Also very important do not get the weed product on any of the bush's leaves or branches. I use a weed product that is organitc and has never killed anything but my weeds. Please note that I have nothing fancy or expensive in my yard. So a little care and some manual work you will have a weed free lawn and healthy bushs.
