摘要
罗素生物公司于2017年6—9月,在坦桑尼亚3个地区的冬玉米上进行了3种生物农药Biotrine(5%阿维菌素),Antario(苏云金杆菌+1%阿维菌素),Recharge(金龟子绿僵菌)对草地贪夜蛾的防治效果进行试验。结果表明,在使用生物农药对草地贪夜蛾(Spodoptera frugiperda)进行防控的小区,玉米植株受害率在1%~5%之间,而使用传统农药进行防治的植株受害率在15%~30%之间;在使用生物农药对草地贪夜蛾进行防治的小区,产量比使用传统农药的对照区高2~3倍。
The experimental trials to determine the efficacy of biorational products(Biotrine:Abamectine 5%,Antar?io:Bucciluss thuringiensis and abamectin 0.1%and Recharge:Meterihzium anisoplie)against fall armyworm(Spodoptera frugiperda)were conducted between June and September 2017.Using farmer’s fields winter maize(Zea maize)in;Arusha(Mwandet ward)Kilimanjaro(lyamungo ward)and Morogoro(Ifakara)regions of Tanzania.The products were treated at 14 days intervals after the initial appearance of damage symptoms and presence of 1st and 2nd instars larva in maize by spraying Biotrine first at the rate of 1 ml/L of water,subsequently,Antario at 1 g/L of water and Recharge at 1g/L of water.On the other hand neighbouring farmers were left at liberty to use their common management practices/options.Three separated farms of approximately a hectare for each region were selected to con?stitute an experimental unit,After three months the treated farms were assessed by dividing each hectare into five small plots,twenty plants were examined for each plot to obtain one hundred plants assessed in each hectare,percent(%)damaged plants against undamaged ones were determined,likewise,for untreated farms in neighbouring farms.The results showed that,mean percent damaged plants was less than 5%,achieving a 95%FAW control for bioration?al products treated farms whereby,for farmers practiced farms showed more than 25%damaged plants.This indi?cates the potency of the technology against fall armyworm in Tanzania.
