“…Treated insects with nerium ethanol extract produced the lowest percentage of mortality (45%) and followed by half dose of malathion. These results agree with Tahir et al, 1992 they assessed the toxicity of malathion against rice weevils, also the effect of plant extracts on rice weevils may be refer to its potential substances for best control such as alkaloids in Egyptian henban while, Southon and Buckingham 1989; Harborne and Baxter 1993 mentioned its toxic activities, also Abo El-Ghar and El-Sheikh (1987) found that the N. oleander extract provided 94% seed protection against insect infestation. Significant effect on wheat seed insect infestation for the interaction among storage periods, wheat varieties and seed treatments as illustrated in Table 3, wheat seeds were free from insect infestation directly after treatment.…”

The role of some plant extracts such as scran and nerium, malathion and the mixture of them in protecting wheat seed from storage insects (Sitophilus oryzae L.,) and keeping its quality during storage is demonstrated. The objective of this study was to determine the effect plant extracts, malathion and the mixture of them on protecting seed of some wheat varieties (Sakha 93,Gemmiza 10 and Giza 168) from storage insects (Sitophilus oryzae L.,) as well as its effects on seed quality and insect infestation during different storage periods (0, 6 and 18 months). The main results revealed that: Treating rice weevils with the recommended dose of malathion resulted 100% mortality, meanwhile treating rice weevils with (half dose of malathion+ scran or nerium ethanol extract) increased mortality percentage more than scran, nerium extracts or half dose of malathion. Extend storage period after treatment for 6 and 18 months increased gradually insect infestation and seed dry weight loss and decreased germination percentage, seed and seedlings vigour and carbohydrate percentage, meanwhile seed protein percentage increased with prolong the storage period. Seeds of wheat variety 168 were the least in insect infestation and seed dry loss percentages comparing varieties Gemmiza 10 and Sakha 93. Treating wheat seed with the recommended dose of malathion or mixed with plant extracts or half dose mixed with plant extracts maintains high seed quality comparing the untreated seed. Generally, seeds of wheat varieties (Giza 168, Sakha 93 and Gemmiza 10) could be store for 18 months with maintain good quality seed by treating with malathion (recommended dose) or half dose mixed with nerium or scran extracts.

“…Genus Nerium is represented mainly by one species, viz., Nerium oleander L. all parts of the oleander plant are poisonous (contains three glycoside). Abo El-Ghar and El-Sheikh (1987) found that the N. oleander extract provided 94% seed protection against insect infestation.…”

“…In order to evaluate which treatments were most effective at protecting grain from F1 descendants, different treatments were applied. According to the techniques utilized by ( El-Ghar et al., 1987 ) as in Eq. (1) , the formula of percentage reduction in adult emergence or inhibition rate (% IR) was used to determine which treatment inhibited the emergence of F1 progenies.…”

Common bean (Phaseolus vulgaris L.) is an essential crop for food security and nutrition mainly for Sub-Saharan African’s smallholder farmers. However, the production and productivity of common bean is mainly constrained by Mexican bean beetles, Zabrotes subfasciatus (Boheman). Thus, the objectives of this study were to evaluate the effectiveness of plant seed powders of neem, Hochst and wild marigold, leaf powders of sweet fennel and broad-leaved croton, plant essential oils of neem and Hochst and African cabbage edible oil at different rates against Z. subfasciatus. All parameters at all botanical seed and leaf powder rates showed a significant difference over the untreated control, except for seed damage at 5 g leaf powders of sweet fennel and broad-leaved croton. Neem, wild marigold, and Hochst at the rates of 5, 10, 15 g/ 150 g, and sweet fennel at 10 and 15 g/ 150 g and broad-leaved croton at 15 g/150 g resulted in 96–100% seed protection, reduced emergence of F1 progeny, seed damage, seed weight loss, and were statistically at par with primphos-methyl. All tested botanical powders recorded 87–100% germination. The botanical oils and mustard cooking oil at rates of 0.5, 1.5, and 3 mL per 150 g common bean produced adult beetle mortality in the range of 93–100% and seed protection of 99–100%. Thus, smallholder farmers can use any of the above indicated botanical powders or oils for post-harvest storage depending on their availability against Z. subfasciatus. Further research on the botanical powders and oils under farmer’s storage condition is important.
