Abstract

Many plant extracts could be considered as natural effective tool against yellow mite instead of synthetic chemicals. The research was aimed at studying the effects of plant extracts on Polyphagotarsonemus latus Banks infestation and jute yield production. This experiment was conducted in Manikganj, Bangladesh following randomized complete block design with three replications. Treatments were Neem oil 3% (T1), Neem leaf extract @ 1:30 (T2), Mahagoni seed extract @ 1: 10 (T3) Turmeric powder extract @ 1: 40 (T4), Garlic paste extract @ 1:30 (T5) and control (T6). Percent reduction of mite population was found in neem oil (87.94%), neem leaf extract (85.76%) and garlic paste extract (86.48%) at 72 hrs after spray. After 7 days of spraying, Neem oil treated plot received the best reduction (89.05 %) followed by neem leaf extract (87.03%), Mahogany (79.60%), turmeric (78.02%), and garlic (80.06%), respectively. Neem oil treated plot showed highest fibre yield (2.95tha-1). Control plot showed highest mite infestation with lowest yield contributing attributes. Neem oil/leaf extract and mahogany seed extracts were found effective to control yellow mite infestation resulting higher fibre yield production.

精选植物提取物对大合唱（Corchorus olitorius L.JUTE）多食跗骨虫（BANKS）侵害的杀虫作用

许多植物提取物可以被认为是对抗黄螨的天然有效工具，而不是合成化学物质。本研究旨在研究植物提取物对黄颡鱼侵扰和黄麻产量的影响。本实验在孟加拉国的Manikganj进行，采用三次重复的随机完全区组设计。处理为3%的印楝油（T1）、1:30的印楝叶提取物（T2）、1:10的Mahagoni种子提取物（T3）、1:40的姜黄粉末提取物（T4）、1:30%的蒜泥提取物（T5）和对照（T6）。喷洒后72小时，印楝油（87.94%）、印楝叶提取物（85.76%）和蒜泥提取物（86.48%）中的螨种群减少了百分比。喷洒7天后，印楝油处理地块的还原率最高（89.05%），其次是印楝叶提取物（87.03%）、桃花心木（79.60%）、姜黄（78.02%）和大蒜（80.06%）。印楝油处理小区的纤维产量最高（2.95tha-1），对照小区的螨害率最高，产量贡献率最低。发现印楝油/叶提取物和桃花心木种子提取物可有效控制黄螨侵扰，从而提高纤维产量。
