Budget Pick
Our budget pick is the Bayer Advanced Crabgrass Killer spray. It’s concentrated, which means that it will need to be mixed with water according to the directions.

Spectracide Weed Stop Concentrate

Review
Spectracide is one of the best-working brands that you can get on a budget. This spray is concentrated, but it’s already ready to spray. It has a special, unique nozzle where you attach the hose to the back opening. When you turn the hose on, the formula mixes in the nozzle so you don’t have to mix it in a separate sprayer – which can get costly. Instead, you simply spray from there and you get the perfect amount of poison vs water. This nozzle really takes the guesswork out of spraying your lawn! There are visible results just eight hours after you spray, and we think that’s pretty amazing! It even kills the almost-immortal yellow nutsedge, as well as 250 other types of weeds. It even gets dandelions! It won’t harm the rest of your lawn, either. Our guide just wouldn’t be complete without a Spectracide crabgrass killer review. For best results, apply during temperatures between 45 and 90 degrees!

BONIDE Weed Beater Plus

Review
BONIDE makes one of the best rated crabgrass killers that we found on our list. It’s super effective at getting rid of crabgrass and other broadleaf weeds really quickly, so you can spot-treat your lawn without harming the turf grass that you want to flourish. Because it doesn’t contain any fertilizer, many people say that this killer works better than other brands for them. If your weeds are particularly stubborn, this might be just the product that you need! It’s ready to use and not concentrated, so you don’t need to do any heavy-duty mixing. It works to kill the crabgrass and other weeds after they germinate – so you have to already see them for this product to work. But once it does, it works well. The smaller size of this product makes it perfect for spot treatment when you have trouble areas but don’t really want to treat your whole lawn. Because it’s not a preventative treatment, it’s perfect!

Jonathan Green Crabgrass Preventer

Review
It might not be a very well-known brand, but that doesn’t mean that Jonathan Green Crabgrass Prevention granules are any less effective. Use them in spring before everything starts blooming or germinating. It works best when used in fully-established grass and lawns, with grass that is passed the seedling stage. This 12.5-pound bag will cover a lawn that is 5,000 square feet in size. It is ideal even for landscaping areas because it won’t harm your other plants – it only works on broadleaf weeds and crabgrass. In fact, it is the best pre-emergent crabgrass killer that we found to work even on flower gardens. This preventative treatment will control your weeds all season long – so you only need to apply it once. It also prevents any other unwanted annual grasses – while protecting your lawn and keeping your existing grass and ornamental plants looking great! We love this formula, and the effectiveness really can’t be beaten.
