在青椒生产中,病毒病、枯萎病和炭疽病是时常发生的病害,严重影响到青椒的产量和质量。现介绍几种“无公害”防治方法1.叶面喷洒硫酸锌防治青椒病毒病。在秧苗四叶期、定植后10天、盛果前期、盛夏后各喷1次硫酸锌0.1％水溶液,可推迟病毒病的发生,并可提前开花,增加座果率。2.喷洒NS—83增抗剂。将83增抗剂药液摇匀,加水稀释成100倍液喷雾。如制剂凝固,可将药瓶放在60℃温水中,待融化后摇匀稀释使用。一般在苗期喷洒两次,定植后15天再喷一次。喷洒均匀,以药液滴流为度。
In the production of green peppers, virus disease, blight and anthracnose are the frequent diseases which seriously affect the yield and quality of green peppers. Now introduce several “pollution-free” prevention and control methods 1. foliar spraying zinc sulfate prevention and treatment of green pepper virus disease. In the four-leaf seedling stage, 10 days after planting, pre-Sheng Sheng, spray after spraying 1% zinc sulfate 0.1% aqueous solution, can delay the occurrence of virus disease, and flowering in advance to increase the rate of fruit set. 2. Spray NS-83 antagonist. Shake the 83% anti-irritant solution and dilute it to 100 times with water. Such as the preparation of coagulation, the bottle can be placed in warm water at 60 ℃, to be diluted after thawing use. Generally spray twice in seedling stage, spray again after 15 days of planting. Spray evenly, to drug droplet degree.
