The planting area of ​​wheat in Jianchuan County is 6-7 million mu, accounting for 60% of the total area of ​​the food crop in Xiaochun. The losses caused by diseases such as barley stripe, powdery mildew, and wheat stripe rust increase year by year. Diseases such as diseases and net spot diseases also have an upward trend. Many diseases of wheat crops can be transmitted through seeds, especially diseases such as barley stripe disease, wheat stripe rust, and smut, which, once they occur, have a great impact on the yield. Seed treatment is an effective measure for the prevention and control of wheat species disease transmission. Currently, it is the best seasonal cultivation of barley in our county. The township agricultural technical departments should pay great attention to it, strengthen publicity and technical guidance, and effectively grasp the seeds before sowing. Processing work.
I. Agricultural control
1. Select disease resistant varieties. Barley selected Rudong 7, Xiumai 3, S500 and other varieties, wheat selected 87-3, 7916, Fengmai 24 and other varieties.
2. Seed screening: Using methods such as wind and sieve selection, the insects, pods, diseased grains and weed seeds in the wheat seeds are removed to ensure the germination rate of the seeds.
3, the sun seed: seed before sowing the first sun for 1 to 2 days, through the sun's ultraviolet rays kill the seed surface bacteria, promote seed maturity, enhance seed vitality and germination rate.
4, a reasonable rotation. Do not repeat the cultivation of single crop varieties. Vibrio, rape, barley, wheat and other spring crops should be properly rotated.
5, timely sowing. The timing of wheat planting is in late November and the barley planting period is suitable from late October to mid-November.
Second, drug seed dressing technology
1. Use 10% difenoconazole WG for seed dressing with 2 g per 1 kg of seeds, which can effectively prevent and control barley striae and net spot.
2, with 15% triadimefon (triadimefon) wettable powder 50 grams of mixed wheat seed 25 kilograms, triadimefon seed dressing can only dry mix, mixed with seeds must be broadcast on the same day, otherwise affect the germination rate, can effectively prevent and control wheat Powdery mildew and stripe rust.
3, with 6% tebuconazole suspension (rickson) 10 ml plus 300 ml of water dressing 20-25 kg, fully mix and boring for 2 to 3 hours, until the liquid is sowed after seed sowing, can be effective Prevent and control smut.
Third, note:
1, the dose of the drug treatment can not be too high, to prevent the damage of seed germination.
2, when mixing drugs to do their own protection, dressing indoors should pay attention to ventilation.
3. Disinfected wheat seeds should not be piled too thick to prevent mildew or germination of the seeds.
4. Sterile excess wheat seeds cannot be used as feed to prevent livestock poisoning.
