Problems solved by technology
However, fluroxypyr is ineffective against gramineous weeds, and its herbicidal spectrum is limited, so it is often mixed with agents for controlling gramineous weeds
[0007] At present, lawn herbicides are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of lawn weeds. Long growth, excessive dosage or uneven application will easily cause residual toxicity to surrounding flowers and crops or subsequent flowers

The invention belongs to the field of pesticides, and discloses a herbicide composition containing dithiopyr and fluroxypyr and application thereof. In the herbicide composition, the dithiopyr and the fluroxypyr are taken as main active ingredients, wherein the mass ratio of the dithiopyr to the fluroxypyr is 1-80: 1-80, and the dithiopyr and the fluroxypyr account for 1 to 85 percent of the total mass of the herbicide composition. The herbicide composition can be used for preparing a herbicide for controlling post-emergence weeds in a lawn, has an obvious effect when used for preparing herbicide for controlling pre-emergency weeds in a planted lawn, and is particularly suitable for preparing herbicide for controlling tall fescue and bluegrass in a lawn. Compared with a single-composition herbicide, the herbicide composition postpones the resistance of weeds, has a broad herbicide spectrum and acts for a long time on the premise of improving herbicide effect, and is safe for the lawns and the succeeding crops.
Description
technical field [0001] The invention belongs to the field of pesticides and relates to a herbicidal composition, in particular to a herbicidal composition containing thiopyr and fluroxypyr and an application thereof. technical background [0002] A problem that cannot be ignored in lawn construction is emphasizing planting and neglecting cultivation, especially the harm of weeds is becoming more and more serious, which makes the lawn beyond recognition. The harm of lawn weeds to the lawn is not only to compete with the lawn for glory, fertilizer and space, but also to dilute the effect of the lawn and reduce the aesthetic value of the lawn. The damaged turf plants are slender and fragile, with reduced resistance to cold, drought, and trampling, which makes the lawn easy to degrade and die, and even cause grass shortage. Therefore, weed control is the key in lawn planting. [0003] The weeds that harm the lawn are nothing more than the following three categories: one is gra...
