Dithiopyr is the active ingredient found in the popular herbicide Dimension, among others. As a preemergent herbicide, dithiopyr is only effective if applied before the target weeds emerge. One of the common uses of dithiopyr is to prevent crabgrass from popping up lawns in the spring.
What is Dithiopyr?
Dithiopyr is the active ingredient found in the popular pre-emergent heribicide Dimension. This pre-emergent is effective at preventing the target weed seeds from germinating, and needs to be applied to weeds before they emerge from the ground. Dithiopyr is a popular active ingredient in weed prevention products and is often used to prevent crabgrass from growing in home lawns and yards in the spring.
How does Dithiopyr work? (Mode of Action)
Dithiopyr controls weeds by disrupting microtubules which are neccessary for plant growth, so essentially the target weeds are not able lto grow. It is important to make the distinction that pre-emerent herbicides do not destroy weeds entirely but rather prevent growth. That is why they must be applied annually to retain the desired effects.
Dimension Herbicide is a specialty preemergent herbicide containing dithiopyr. When applied early it effectively prevents the growth of control of crabgrass, crabgrass, goosegrass, chickweed, spurge and Poa annua. Dimension is appropriate for both residential and commercial lawns. Dimension is also proven effective for use on golf courses, sports turf, landscape ornamentals, container- and field-grown nursery ornamentals, commercial sod farms, and noncrop areas including roadsides.
Dithiopyr is toxic to fish but non-toxic to birds. Products containing dithiopyr typically will carry instructions to keep the chemical away from water supplies and areas of runoff so as not to contaminate water.
