进行了一项田间研究，以评估一些植物药防治苋田害虫的功效。印楝的干叶和树皮灰提取物作为处理，与高效氟氯菊酯和对照进行比较。该实验采用随机完整区组设计，重复三次。收集的数据进行双向方差分析，并使用 Fisher 最小显着差异 (LSD) 检验以 5% 的概率水平分离显着不同的平均值。结果显示，经过处理的植物通常比未经处理的植物表现更好，因为它们更高，有更多的叶子、树枝、更宽的茎围，并且果实产量更高。印楝树皮灰提取物在大多数测量参数中表现更好。结果表明，如果利用得当，印楝叶和树皮灰提取物可作为生物农药用于防治田间水楝害虫。收集叶子总数、受损叶子数量、叶子受损百分比、株高、茎围和干重的数据。随机选择五片叶子并标记并用于这些测量。计算每个处理中每株杂草植物产生的叶子数量并记录数量。叶孔数 a 也记录为数量。受损百分比计算如下： 除茎周长外，各处理间评估的生长参数存在显着差异（P<0.05）。喷洒高效氟氯菊酯的植物具有显着最高的植物高度、根长和干重，而喷洒植物提取物的植物与对照植物具有可比的值。结果表明，水性植物提取物对田间害虫A.hybridus表现出一定程度的控制作用，因为与对照相比，它们记录的叶损伤百分比较低。施用植物提取物后叶片受损百分比的降低表明杂草叶害虫数量减少。这也表明提取物具有减少昆虫侵袭的杀虫作用。本实验的结果与 Aderolu 等人的昆虫种群和数量减少的结果一致
A field study was carried out to assess the efficacy of some botanicals in the control of field insect pests of Amaranthus hybridus . Dry leaf and bark ash extract of Azadirachta indica served as treatments which were compared with Lambdacyhalothrin and a control. The experiment was fitted into a randomized complete block design with three replications. Data collected were subjected to a two-way analysis of variance and significant different means were separated using Fishers Least Significant Difference (LSD) test at 5 % level of probability. The results revealed that treated plants generally performed better than the untreated plants as they were taller, had more leaves, branches, wider stem girths and gave higher fruit yield. bark ash extract of Azadirachta indica performed better in most parameters measured. The results indicate that leaf and bark ash extract of Azadirachta indica if properly harnessed can be used as a biopesticide in the control of field insect pest of A. hybridus . Data were collected on total number of leaves, number of damaged leaves, percentage leaf damage, plant height, stem girth, and dry weight. Five leaves were randomly selected and tagged and for these measurements. The number of leaves produced per A. hybridus plant for each of the treatments was counted and the number recorded. The number of leaves holes a was also and the recorded as the number The percentage damaged was calculated as: Significant differences (P<0.05) were found among the treatments in the growth parameters assessed with the exception of the stem girth Plants sprayed with Lambdacyhalothrin had significantly the highest plant height, root length and dry weight while plants sprayed with the plant extracts had comparable values with the control plants. The results showed that the aqueous plant extracts exhibited some level of control of the field pests of A. hybridus as they recorded lower percentage leaf damage in relation to the control. Decrease in percentage leaf damage to the application of the plant extracts is an indication of reduced number of foliage pests of A. hybridus . It is also an indication that the extracts possess insecticidal effects in reducing insect attack. the result in this experiment conform with the of Aderolu et al decrease in insect population and number of
