Summer is the most vigorous weed growth, weeding work must be done, how to achieve good weeding effect, in addition to the use of trustworthy herbicides , we must also know some of the herbicide use in the summer, in order to get the desired results. In the lawn maintenance, weeds are the key project of turf maintenance, especially in the summer, high temperature and rain, weeds grow fast. In the nursery land, the early stage is mainly broad-leaved weeds, and the middle and late stages are mainly 1-year-old grass weeds. The young orchard of Xinyi is dominated by perennial weeds such as striated grass, thatch, thorn, and small convolvulus. There are also 1-2 years old weeds such as crabgrass, goosegrass, foxtail, and purslane. The adult orchard is mainly composed of 1-2 year old grass weeds and broadleaf weeds, and there are also a small number of perennial weeds. Commonly there are teff, wild oat, goosegrass, foxtail, shovel, and twigs. Purslane and so on. Therefore, herbicides should be used in time for chemical weeding. 10% gram of tracer water (also known as paraquat) is a herbicide herbicide, killing grass quickly, stems and leaves will die after 1-2 days, mainly used to control 1-2 years of weeds, for perennial miscellaneous Grass can only kill the aerial parts, but it is less effective against sedge weeds. Control the grass below 15 cm, use 150 ml of water per acre for 30 kg; control large grass of 20 cm or more, use 200-300 ml per acre for 50 kg of water, spray the weeds with directional spray, not Spray or drift the liquid onto fruit trees or other crops, otherwise phytotoxicity will occur. 10% glyphosate water (also known as Nongda, Zhencao Ning) is a systemic extractive herbicide that kills grass slowly, prevents 1-2 years of weeds, and leaves stems and leaves 15-20 days after the drug Will die, to prevent perennial weeds, it takes 25-30 days for the stems and leaves to die, and the rhizosphere gradually rots. Control 1-2 years old weeds 650-1000 ml per acre, 30-40 kg of water. Control perennial deep root weeds 2000 ml per acre, 40-50 kg on water. The application method is the same as the gram tracer. 25% diuron WP can kill the annual weeds of Madang. You can choose 25% diquat WP WP 0.75 kg, add 40-50 kg of water, treat stems and leaves or soil, and achieve good results. 50% simazine wettable powder (also known as simazine) selectively inhales and transports soil-type soil to treat herbicides. It is not toxic to plant roots and has no effect on seed germination. Only after the nutrients in the seeds are exhausted, the seedlings die. The weeds showed signs of suffering 7 days after the application. It can be used to control perennial weeds of 1-year-old weeds and seed propagation, and the efficacy of controlling broad-leaved weeds in 1-year-old weeds is higher than that of grass weeds. Weeds have a good effect before they are unearthed and in the germination period. 150-250 grams of water per 50 acres of wettable powder, sprayed on the soil surface in April-May. Since the residual effect of simazine has an adverse effect on the growth of certain crops, especially when it is dry or rainy, or when the amount of medicine is large, although it is still toxic to sensitive crops every other year.
