It works within two days and is very effective on all weeds.

Very good results particularly on kykuyu which i consider a pest that invades our garden from next door . It took a bit of adjusting the dose to be effective. But with the wet weather now we stopped the process. But during a dry day , within 15 minutes one can see ground cover weeds collapsing.

seed suppression

To every single weed there are a million seeds, so when you pull a weed, or kill with most weed killers, you are still leaving millions of seeds in the ground, so new weeds keep popping up.

While Bioweed is not a pre-emergent herbicide, it does have pre-emergent qualities, as it suppresses seeds on the weed and ground. This is due to when it comes in contact with the seed, it dries out the epidermis or coating. This leads to the seed cracking prematurely and drying out the embryo.

So using Bioweed will not only kill the weed, it will also lower your count of seeds in the ground, which means less applications and waiting time to having a perfect weed free garden.

Popular Questions

Bioweed is not a systemic herbicide but rather works by stripping the outer coating of contacted plant and seed material, causing cell collapse and desiccation. The plant uses its natural water cycle to pull water and energy out of the root system and dehydrate the plants growth system.

Direct contact with seed on the weed or in/on the soil will cause de-naturing of seed coat. This leads to the desiccation of the seed embryo and making the seed inviable.

Bioweed will control a large range of herbaceous and grass type weeds. It will also control the seed of these plants. Bioweed will not control woody weeds such as lantana and devils fig. This is because it works on the waxy cuticle of the leaf and not the lignin (trunk).

Weeds Controlled by Bioweed. 

For best results, shake before use, fully cover target weed to the point of run off, use on a sunny day and don’t use if rain is forecasted in the next 2 hours.

Off target damage is very low. As explained above, Bioweed will not damage tree root systems and trunks. This is because it is not a systemic herbicide. Making Bioweed perfect for control of weeds around new garden planting and valuable plants.

Dependant on the storage of Bioweed, it is registered to have a shelf life of 2 years. (see label)

Bioweed will control most types of grasses. As it is not a conventional herbicide, full coverage of the grass is needed to get full control. If using Bioweed as an edging tool, a fine edge can be achieved as it will not retract back into the lawn area. Please note that when treating mature grasses with ‘runners’ a follow up treatment in 4-7 days will be required.

With no withholding periods Bioweed is safe for pets and animals to use the area immediately after the area is dry. This ensures the weed killer has maximum time on the leaf surface for best results. 

If application manual and label is followed, Bioweed will achieve a full kill of targeted plants.

With no withholding periods, Bioweed is safe for animals immediately after the area is dry. 

Bioweed will control Nutgrass but it will take several treatments to control completely. This is because for every nut grass plant there can be multiple seeds or nuts under the plant. With follow up treatments you will be able to control the plants and also the seed that the plant produces to stop germination in the future. It is important to get full coverage (to the point of run off) of the nutgrass. Best results are seen when applied in the morning of a hot sunny day.
