Pelargonic acid occurs naturally in plants including geraniums. It acts on the foliage, causing it to quickly dehydrate and collapse. Results are seen as browning and wilting usually within 1 hour of application. † Visible results can take longer than 1 hour on certain tough weeds or weeds in shaded conditions. For best results, apply when temperature is over 10°C. To be effective, Slasher® Organic* Weedkiller must come into contact with the green parts of the plant. Slasher® Organic* Weedkiller will control many weed species and is non-selective. **MIXING:** Half ll spray tank and commence agitation. Slowly add required amount of Slasher® Organic* Weedkiller. Top up with required quantity of water. Agitate well before commencing spray procedure. Do not mix more than is needed. **APPLICATION:** Ensure that all weed foliage is totally covered with spray as Slasher® Organic* Weedkiller is a contact spray only. Partial coverage will give only partial control. Apply by ground equipment only using for example boom or spot sprayers. Apply using a coarse droplet spray. Optimum application volumes are related to weed maturity and density. Contact with the weeds is essential for control, as such apply in sufcient water to ensure complete and thorough coverage of foliage. DO NOT spray porous surfaces without prior testing. May cause discolouration on porous hard surfaces. **PRECAUTIONS:** Wear eye protection when mixing or using. **RE-ENTRY PERIOD:** Do not enter treated areas until the product has dried. **PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS:** DO NOT apply under weather conditions, or from spraying equipment, that may cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures. **PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT:** DO NOT contaminate wetlands or watercourses with this product or used containers.
