防治大棚草莓病蟲害的幾種藥劑
葉斑病 又稱蛇眼病,主要為害葉片、葉柄、果梗、嫩莖和種子。在葉片上形成暗紫色小班點,擴大后形成近圓形或橢圓形病斑,邊緣紫紅褐色,中央灰白色,略有細輪,使整個病斑呈蛇眼狀,病斑上不形成小黑粒。  使用藥劑:發病初期用70%百菌清可濕性粉劑500倍~700倍液,10天后再噴一遍,或用70%代森錳鋅可濕性粉劑,每667平方米200克對水75千克進行噴霧。  白粉病 主要為害葉片,也侵害花、果、果梗和葉柄。葉片上卷呈湯匙狀。花蕾、花瓣受害呈紫紅色,不能開花或開完全花,果實不膨大,呈瘦長形;幼果失去光澤、硬化。近熟期草莓受到為害會失去商品價值。  使用藥劑:在發病中心株及其周圍,重點噴布波美0.3度石硫合劑。采收后全園割葉,噴施70%甲基托布津1000倍液或50%退菌特800倍液及30%特富靈5000倍液等。  灰霉病 是開花后的主要病害,在花朵、花瓣、果實、葉上均可發病。在膨大時期的果實上,生成褐色斑點,并逐漸擴大,密生灰霉使果實軟化、腐敗、嚴重影響產量。  使用藥劑:于現蕾到開花期進行防治,用25%多菌靈可濕性粉劑300倍液、50%克菌丹可濕性粉劑800倍液、50%撲海因500倍~700倍液等噴霧。  根腐病 從下部葉開始,葉緣變成紅褐色,逐漸向上凋萎,以至枯死。支柱在中間開始變成黑褐色而腐敗,根的中心柱呈紅色。  使用藥劑:草莓移栽前用40%蘆筍青粉劑600倍液,澆于畦面,然后覆土,整平移栽,以有效殺死土壤中的病菌,降低田間菌源基數,減少傳染機會。    黃萎病 該病是土壤病害,主要癥狀是幼葉畸形,葉變黃,葉表面粗糙無比。隨后葉緣變褐色向內凋萎,直到枯死。  使用藥劑:嚴格引入無病植株種植,縮短更新年限;用氯化苦13.5升~20升進行土壤消毒;已發病者必須拔除燒毀。  蚜蟲 它對草莓為害是因吸取汁液使果實生育受阻,同時也因蚜蟲排出甘露而讓葉、果受到污染。另外,蚜蟲也是傳播病毒的媒介。  使用藥劑:及時摘除老葉,清理田間,消滅雜草。開花前噴布50%辟蚜霧2000倍液,共噴施1次~2次。  紅蜘蛛 為害草莓的以紅蜘蛛、黃蜘蛛為主,尤其紅蜘蛛為害更多。葉片初期受害時出現小灰白點,隨后逐步擴大,使全葉片布滿白色花紋、黃化卷曲,植株矮化枯萎,嚴重影響生長。  使用藥劑:花序初顯時,可噴0.3度石硫合劑,隔七天再噴一次。采果前用殘毒低的20%增效殺滅菊酯5000倍液~8000倍液,噴二次,間隔五天。注意采果前二周禁用農藥。
