導讀:2月下旬低溫持續(xù)時間長,冬油菜正處于現(xiàn)蕾抽薹至開花初期,降雪或凍雨等低溫寒潮天氣導致部分油菜葉片受凍、蕾薹結冰、莖桿破裂,生長放緩,抵抗力降低,增加了油菜菌核病感病風險。

  【農機網 科技創(chuàng)新】 今年2月以來,長江流域冬油菜主產區(qū)連續(xù)遭遇兩輪大范圍低溫雨雪冰凍天氣過程。尤其是2月下旬低溫持續(xù)時間長,冬油菜正處于現(xiàn)蕾抽薹至開花初期,降雪或凍雨等低溫寒潮天氣導致部分油菜葉片受凍、蕾薹結冰、莖桿破裂,生長放緩,抵抗力降低,增加了油菜菌核病感病風險。隨著氣溫回升,田間溫潤條件會進一步促進菌核病菌核提前萌發(fā)產生菌絲或者子囊孢子進而侵染油菜莖基部。據國家氣候中心預測,3月份我國江淮南部、江漢東部、江南東北部等地降水量接近常年或偏多2—5成,存在階段性低溫陰雨寡照天氣,增加農田濕度和漬害。油菜成熟期菌核病提早加重發(fā)生風險較高。為做好2024年油菜菌核病防控工作,確保油菜生產安全,特制定本方案。
 
  一、防控目標
 
  防控處置率總體達到90%以上,統(tǒng)防統(tǒng)治覆蓋率50%以上,防治效果達到70%以上,危害損失率控制在8%以下。
 
  二、防控策略
 
  采取“預防為主、綜合防控、統(tǒng)防統(tǒng)治”的防控策略。加強田間管理,抓住關鍵時期實施防控,應用無人機等植保高效施藥器械進行統(tǒng)防統(tǒng)治。
 
  三、防控重點及技術措施
 
  (一)分區(qū)防控重點
 
  1前期受凍油菜區(qū):湖北、湖南、安徽、河南、江蘇及貴州部分地區(qū)油菜受凍較重,注意重點防控。
 
  2.重發(fā)區(qū):湖北、湖南、安徽、江蘇、江西、浙江為菌核病重發(fā)區(qū),注意重點防控。
 
  3.常發(fā)區(qū):重慶、四川、貴州、河南信陽和陜南地區(qū)為菌核病常發(fā)區(qū),注意關鍵期防控。
 
  4.輕發(fā)區(qū):云南、陜西關中、甘肅、青海、新疆和內蒙古等為菌核病輕發(fā)區(qū),注意監(jiān)測,適期防控。
 
  (二)主要技術措施
 
  1.農業(yè)防治。一是及時清溝理墑、排澇降濕,確保田間排水順暢、不留漬水,降低田間濕度,抑制菌核萌發(fā)。二是追肥調控,促進生長,對發(fā)生凍害的田塊,每畝施用3-5公斤尿素和3公斤氯化鉀,增強抗逆性。
 
  2.生物防治。菌核病發(fā)生初期,可采用盾殼霉、木霉菌或地衣芽孢桿菌等生物菌劑進行施藥防治。
 
  3.化學防治。對于蕾薹期油菜菌核病,田間明顯可見油菜莖基部感病時,應及時噴施氟唑菌酰羥胺、腐霉利、咪鮮胺等藥劑進行防治,藥液要求噴施到植株莖基部。對于成熟期油菜菌核病,可根據當?shù)貙嶋H情況合理安排施藥時間、次數(shù)以及配方。在菌核病輕發(fā)區(qū)和常發(fā)區(qū),建議于開花始盛期(田間有50%以上的植株開花)防治一次;在菌核病重發(fā)區(qū),建議于初花期和盛花期各防治一次,兩次之間間隔7-10天。藥劑可選用新型殺菌劑氟唑菌酰羥胺、啶酰菌胺或常規(guī)殺菌劑咪鮮胺、腐霉利、異菌·氟啶胺等??商砑哟\、乙蒜素等兼治細菌性軟腐??;也可添加赤·吲乙·蕓苔、二氫卟吩鐵、13.4%氨基酸水溶肥·生物激活劑水劑、新美洲星等提高油菜抗病抗逆能力。
 
  四、注意事項
 
  一是嚴格按照無人機作業(yè)規(guī)程進行施藥,建議添加飛防助劑,減少霧滴漂移,提高防治效果。
 
  二是選用對蜜蜂安全的藥劑品種,避免花期施藥對蜜蜂的不良影響。
 
  三是嚴格按照規(guī)定劑量和濃度施用農藥,注意輪換用藥以延緩抗性產生。
