Active components

This weed killer has a few active components for better effects: 

  • 0.104% Quinclorac; 
  • 0.313% 2,4-D dimethylamine salt; 
  • 0.029% Dicamba, dimenthylamine salt;

Broadleaf weeds are killed by 2,4-D, but most grasses are not. Auxin-type herbicides are herbicides that include this chemical. 

2,4-Dichlorophenoxyacetic acid (2, 4-D) belongs to systemic herbicides that target broadleaf weeds and destroys them selectively. It kills weeds by changing the way the cells of these plants develop, causing them to die. In other terms, it stimulates unchecked cell development in broadleaf weeds, causing them to die.

Quinclorac is a quinolone carboxylic acid that acts as an auxin mimic. The vegetation absorbs it and transports it across the vine. Broadleaf weeds display symptoms such as leaf and stem curling or bending, as well as necrosis.

Dicamba is a herbicide equivalent to 2,4-D. Both function as auxins, which are normal plant hormones. These hormones aid in the regulation of plant development. When plants are handled with Dicamba, they grow in uncontrollable and unnatural ways, and they sometimes die.

What weeds can it kill? 

It has the potential to kill over 200 plants, including broadleaf weeds including dandelions and grassy weeds including annual crabgrass. As for other herbicides, the quality and effectiveness of this substance are contingent on following the package instructions and safeguards.

It’s important to remember that this substance isn’t meant for flower beds and may kill shrubs. It’s also not suitable for people and pets throughout the application and after the substance has completely dried, since it may affect Bermuda grass to yellow. It’s also not useful on hot days above 90 degrees Fahrenheit.

Tips for users: never apply on Southern grass, St, Augustine grass, Bahia grass, Carpet grass, Centipede grass.

How to use it?

You’ll need to estimate the region of your yard that you’ll be treating with BioAdvanced so that you can add the correct number. Measure the length and width of the yard, so multiply the two figures to get the treatment region in square feet.

Since BioAdvanced is fully concentrated, 3.2 fluid ounces (6 1/2 tablespoons) can dissolve in 1 gallon of water. This volume is enough to cover 500 square feet. If your lawn is very dusty, water it completely 1 or 2 days before applying BioAdvanced.

You should use a hose-end sprayer or a pump-style tank sprayer, all of which should be loaded no higher than the fill line indicator. A hose-end sprayer is best for treating vast fields or the whole lawn, whereas a tank-style sprayer is good for spot treatments of weeds in your garden.

Simply apply the BioAdvanced product to the area of your yard the furthest from the water faucet with a hose-end sprayer, walking backward to prevent touch with the treated area.

When to use it? 

  • The regular maximum temperature should not reach 90 degrees Fahrenheit (85F for Bermuda grass). Apply on warm and calm days;
  • Use it when the weeds are small and actively growing;
  • The effectiveness of the product would not be harmed by rain at least during 1 hour after application;

Delay until the fourth mowing to sprinkle BioAdvanced on a newly seeded lawn, and 1 to 2 days after spraying an existing lawn before mowing. Wait 4 weeks after spraying BioAdvanced before seeding some bare spots. BioAdvanced can be applied on a non-windy day to avoid the spray drifting through the lawn or vegetable plants.

Where to use it?

It is recommended for such areas of use as lawn, flowerbeds, around trees and along fences. It is better not to spray it on useful grasses and edible plants. 

How long does it take to work? 

According to the manufacturer, this product shows the first visible results within 12 hours after application. The claimed duration of its effect lasts about 30 days.

The Buyer’s Guide

Mode of action

This herbicide destroys weeds until they germinate. Pre-emergent herbicides stop sprouted weed seedlings from establishing themselves by inhibiting root, shoot, or both development. To be successful, the herbicide must be introduced into the soil through rainfall or irrigation, and it must be present when the weed seeds germinate.

It’s also a targeted herbicide, meaning it’s designed to kill weeds in your yard without harming most grass species.

Ease of use

This broadleaf herbicide can be spread to the whole lawn if used as instructed. Its advanced formula kills weeds at the root while keeping the grass safe. It has SmartTrack, which briefly tags weeds with a red stain and stays successful in the rain for up to an hour.


Is it safe to use around wood shrubs in the boxes? 

Yes, but you should spray it directly on the weeds that you wish to kill. The red ink makes it easy to tell where it lands. 

Will it kill tulips on flower beds? 

It should not kill grass or flowers but you should never spray it on any plants you want to keep safe. 

Can it cope with Nipplewort (Lapsana)?

You may try if this weed is broadleaf.
