5% oxazoline-fossilicide is a herbicide developed by Swiss Syngenta Crop Protection Co., Ltd., in order to clarify the control effect of barley weeds and barley weeds in barley fields and the safety of barley weeds, and the coastal areas of Jiangsu Province. Zhou Jiachun and others from the Institute of Agricultural Sciences conducted a field efficacy trial and achieved good results. Test field grass weeds to see aunt, hard grass, wild oats, pre-winter and spring, respectively, per acre with 5% oxazoline EC 60 ml, 80 ml and 100 ml, control agent 50% isopropyl Long wettable powder with 125 grams per acre before winter, 250 grams per acre in spring, were added 30 kg of water spray. 20 days after pre-winter application, it was observed that 5,000 oxazoline ECs were yellowed to varying degrees in all grasses, while 50% iplonol WP was used to treat grassy weeds without obvious yellowing. The effect of oxazoline emulsifiable concentrate was significantly faster than that of 50% isopropenol wettable powder. After 15 days of application of the pesticide in spring, it was observed that the grass weeds were yellow in all treatments, but the yellowness of the weeds treated with 5% oxazoline emulsifiable concentrate leaves was more obvious; 0% oxazoline oxalate cream was applied 20 days after application. Treatment of grass weeds began to die. After 1,3,5,7 days after spraying, the growth status of barley seedlings was investigated, and no abnormalities were found, indicating that 5% oxazoline EC was safe for barley growth within the above dose range. After observing the situation of seedlings of the post-harvest direct-seeded rice, the seedlings were also free from injury. According to the survey data, 80 ml of 5% oxazoline emulsifiable concentrate was used per acre before winter, and the control effect of the strain against gramineous weeds was up to 72.99% after 30 days after application, and 120 days after the application of the drug against gramineous weeds. The control effect of the strain was 91.92%, and the fresh weight control effect was 94.89%, which was significantly higher than the control effect of 125 grams of 50% isopropenol wettable powder per acre for the same period (corresponding control effects were 50.65%, 64.85%, and 70.66, respectively). %); spring per acre with 100 ml of 5% oxazoline EC, 30 days after application of the grass weed control effect of up to 82.18%, 60 days after drug control against grass weeds can be Up to 96.26%, fresh weight control effect of 97.61%, also significantly higher than the same period with 50% isopropylamine WP 250 grams of control effect (corresponding control effect was 65.95%, 75.24%, 77.35%). The test results showed that 5% oxazoline emulsifiable concentrate can be used to control a large number of grassy weeds in barley fields. It is safe to barley in the above-mentioned dose range, and it is also safe for transplanting and direct seeding of rice. It is recommended that 80 ml per mu be used before winter and 100 ml per mu during spring. After the winter application, the continuous low temperature and rainy weather did not affect the safety and efficacy of barley. Only the death time of weeds was postponed. When the temperature was high in spring, the speed of weeding was significantly accelerated.
