Thrust Selective Weed Killer 5L
Thrust Selective Weed Killer 5L Highly effective on ragwort. Also offers control on broad-leaved weeds such as thistle, dock, plantain, soft rush and buttercups. Ideal for paddocks and pasture as it is safe for grass. Great value for money. Full Description Activate-G has been specially formulated to combine with the active ingredient of herbicides to improve their uptake into the plant. This is done in two ways, firstly by stopping the pesticide 'locking up' when used in areas of hard water and secondly by helping the chemical absorb into the plant using its unique 'uptake system'. Using Activate-G stops any loss of active ingredient as it is drawn into the plant rather than sitting on the surface and evaporating or running off. Mixing Activate-G with herbicides such as glyphosate and grassland products has significantly enhanced the speed and effectiveness of the kill. Typically, adding in this product increased the activity of herbicides by 7-10 days and helped reduce the time taken for the herbicide to dry on the leaf by several hours. This can be particularly helpful in times of poor weather conditions. In short, adding Activate-G enhances the effect of herbicides by around 25%. Using Activate-G can be very useful when trying to countrol tough, waxy plants, or when trying to penetrate large, dense foliage. For smaller areas, consider using the smaller pack of Activate-G 1L. Our Recommendation Always read the product label before use. Save time and money and mix in Blue Dye to ensure no areas are missed or overdosed. For great weed killing results mix in with a Glyphosate-based weedkiller such as Gallup 360. Always wear protective clothing, such as Chemical Resistant Gloves, when handling Activate-G.
