棉花枯萎病在陕西关中,近几年由局部地区发展到点面发生,蔓延速度和面积已超过黄萎病。一般发病和死苗在30—50%,严重的棉田在90%以上。一些黄萎病区逐渐转为枯、黄萎混合发生区,枯黄萎同株型极为普遍。此病在棉花苗期即表现症状,潛育期为10—20天。1—2片真叶发病率达10—15%;5—6片真叶(蕾期)即会引起大量枯死和萎蔫。土壤致病温度平均在20°—25℃,维持10天以上,发病最烈;28℃以上病势减轻。土壤含水量在60—75%之间,枯萎病发病率最高。每年枯萎病发生消长与5、6月份的温、湿度及降雨量有一定关系。以4—6片真叶期,枯死植株发展较快,开花后期枯死率显著下降,到吐絮期尚有高峯出现。各品种间的枯死规律基本相同;仅有枯死程度上的差异。防治棉花枯萎病主要途径以抗病品种为主。由1956—1961年已鉴定出抗病品种(系)有52-128、鸭棚、147-Φ、57-50、南通二号、F96,F80等。其中确定能在病区生产应用的有52-128,鸭棚,平均降低发病率在30—70%,增产15—40%左右。并发现抗病免疫类型有中棉“嘉定硬子”。远缘杂交材料(353×G 1472)×芙蓉葵353 F_2可作杂交原始亲本材料。在病区...

This method has been conducted under the natural conditionsin Spring and Autumn at Sichuan for five years for screening anddetermining the wilt-resistance of cotton stocks.The results indicatedthat the wilt-resistance of cotton plants in the seedling and squaringstage was the same.

棉花品种抗性的苗期鉴定方法,以5-10克/尺~2棉籽菌粉接种2寸深土壤,土温23℃左右,土壤湿度在初见病前50-60%,后期70%左右,促进发病加重,缩短鉴定历期,在出苗后25天,可确定不同品种的抗性。七年来利用我省自然气候特点,春、秋季进行苗期抗性鉴定,筛选杭病材料。早期鉴定品系抗性,证明了棉花品种苗期鉴定的抗性与蕾期发病趋势基本一致。

The incidence of the cotton wilt in-the vicinity of Beijing(Peking)generally reached 10—30% and in ceratin cases upto 50%.In fieldobservations it was found that the disease began to appear when theaverage temperature rose to 20℃,reached its peak at about 24℃and began to decrease when the temperature rose above 28℃。Thecotton plants were infected throughout the growth period,however,the most abundant disease development occurred in the time of ballformation.When the infested soil was in presence of an unidentifiednematode,the disease incidence was significantly increased.In thefield plot where only Fusarium culture was inoculated,the percentageof diseased plants was 51.5%.However,when both Fusaium cultureand nematodes were inoculated,the percentage of infection was increa-sed upto 65.6%.It was determined that the cotton variety Shaan 721was highly resistant to the Fusarium wilt with disease indices 0.6—4.8while the susceptible control variety Xuzhou 1818 showed disease indi-ces 31.5—35.4.The infested soil after being treated with nematcidesin mixture with fungicides resulted the most satisfactory control.Apractice of 3—4 years crop rotation of cotton with wheat,corn orpaddy rice reduced the disease incidence nearly by 95%.

棉花枯萎病在北京市郊区当日平均温度20℃时,棉田开始发病,24—28℃时,发病最烈,低于24℃或高于28℃时,病势减轻。相对湿度在80%以上,发病严重。棉花从苗期到吐絮期均能受其侵染为害,以蕾期受害最重,发病率达20.9—60.6%。防治棉花枯萎病应采取以种植抗病品种为主的综合防治措施。1973—74年,鉴定出陕721品种属高抗类型,蕾期发病率2.5—8.9%,病情指数31.5—35.4;药剂防治采用杀线虫剂滴滴混剂和杀菌剂多菌灵按10:2作土壤处理,蕾期防效可达85.2—100%,比单施杀菌剂或杀线虫剂防效提高20—30%,与小麦、玉米、水稻轮作3—4年,病害可减轻95%以上,病叶、病秆经高温(煮沸后再煮半小时以上)处理,病菌能被杀死。经处理的病叶喂猪,猪粪不带菌。无病土育苗移栽,发病率21.4%,直播棉田发病率63.3%。
