At first the result. The weeds in the lawn proportion fell sharply from an estimated 10% to now only very vereinzelnd standing Dandelion plants have survived the attack. The mixing is relatively easy. Wherein said means is two liquids contained in two small vials and diluted with water. The dosage using the vial has not at least helped me. The best way to buy a syringe for dispensing. My experience: the grass is not cut too short (so enough leaves present) nor suffer too long (thus can trickle down the middle on everything). I made the mistake of each seedling spraying individually, thereby making this approach a lot of effort and you always forget which. Next time I'm going to spray all over the lawn evenly because that's faster and more efficiently. Is good to know that this drug stimulates plant growth strong and the plant grows to death. This also means that it takes a while until it worked and the better the lawn was fertilized and waters, the faster this process goes well. After 1.5 weeks, I would guess you are then free from weeds. Associated health risks is not this means. My research has shown, however, that it is not particularly toxic or harmful. It is very good that it degrades within a few days by itself in the plants and then also no longer be detected in the lawn.
