Proliance Quattro 10 Litre Total Weedkiller / Herbicide Proliance Quattro roundup Weedkiller. For more active weed control, spray ahead with Proliance Quattro Roundup Weedkiller. Proliance Quatro Roundup weedkiller is an advanced glyphosate formulation which incorporates a fully optimised surfactant system and water conditioner. Proliance Quattro roudup weedkiller applied to foliage is translocated through the plant, controlling all parts including roots, rhizomes and stolons. After treatment discolouration of the leaves is seen first on grass weeds but takes longer to appear on broad-leaved weeds. The time or complete kill of weeds depends on species and growing conditions, and may vary from a few days to a few weeks.To allow Proliance Quattro to translocate to maximum effect, it is important that perennial weeds are not broken up before treatment, so cultivation should not be carried out before spraying. Extreme care shoiuld be taken to avoid spray drift as this can severley damage neighbouring crops or plants. Do not spray in windy weather, especially if applying a spray with small droplet size. In good growing conditions Proliance Quattro is rainfast within 6 hours. Where weed growth and uptake is slowed by adverse conditions, a rain-free period of up to 24 hours following spraying may be necessary.Total weedkiller kills roots.
