Amvista Spore Stop is a highly effective tool in ProGreen Mare's Tail/Horsetail control range. It has been designed and developed to minimise the spread of Horsetail via its spores and completes the full control programme. Amvista Spore Stop and Kurtail Evo and KPlus are the one-two knockout for mare's tail control. Spore Stop prevents the spread, Kurtail controls the weed.

Horsetail Weed has two main growth stages: a reproductive stage that appears as a pale brown stem topped with a cone-shaped spore releasing structure; and the sterile green fern-like growth which smothers out other plants. Kurtail Evo has long been established as the strongest weedkiller for the green fern stage and now Spore Stop has arrived to prevent spores colonising new areas, neighbouring properties and reinforcing populations of mare's tail being controlled with Kurtail Evo.

Key points:

• Coats the spore releasing structure with a long lasting barrier preventing spore release.
• Formulated with a powerful surfactant to give even coverage across the full surface reducing reliance on complete coverage.
• Fits perfectly into sequence with Kurtail Evo Horsetail strategy. Spore Stop prevents the Spread, Kurtail controls the weed.
• The reproductive stage can begin releasing spores soon after emerging. The exact timing is very weather dependant. The cone first emerges as a solid structure, Spore Stop should be applied as this begins to open.
• 5ml to 1ltr dilution
