| dc.description.abstract | Sorghum, Sorghum bicolor is an important cereal crop in Ethiopia, sorghum grains are severely destroyed by insects and other storage pests under unsafe storage conditions. One of the primary causes of grain loss in stored sorghum is the damage caused by maize weevil, Sitophilus zeamais. A study was conducted to assess the sorghum post harvest pest’s distribution, damage/loss and evaluate selected locally available botanicasl such as : Neem, Peeper, Finger Millet mix and Eucalyptus wood ash for their effectiveness against maize weevils at Tach Armacho in the year 2017. The natural products were compared with untreated control and Malathion 5% dust as standard check. During the survey baseline data were recorded. The S. zeamais management experiment was laid-out in Completely Randomized Design with 9 treatments each replicated three times. The highest sorghum grain germination was obtained from grain treated with Eucalyptus Wood ash @ of 62.5 grams and Wood ash @ of 125 grams. Likewise, the highest sorghum grain germination (42.03% seedlings) was obtained from Malathion 5% dust @ of 0.25 grams at 5th days followed by Neem seed powder at 10 and 5 grams. After the 40th days of adult moths introduction, sorghum grain moth was emerged from the controlled treatment (28.0%), Pepper powder at 1grams (1.67%) and Finger Millet mix @ of 125 grams (1.33%). Throughout the experiment, the standard check Malathion 5% @ of 0.25 gram gave 100% adult mortality over time where as treatment (Neem seed powder at 10 gram), (Eucalyptus Wood ash at 62.5 gram and (Eucalyptus Wood ash at 125 gram) gave 100 % adult mortality rate after the 10th days of exposure. The cumulative minimum mortality after 25 days of exposure (26.67%) was registered from the control treatment, followed by Pepper powder at 5gram (63.33% adult mortality). The partial budget analysis showed the highest net benefit of Birr 15678.5 ha-1 was recorded from treatment (Ash 62.5g) and treatment (Ash 125g). Even though, Ash @ of 62.5g and 125g resulted similar net benefit and total cost that vary, they are different in amount (dose). Thus, from the economic point of view, treatment Ash @ of 62.5g could be recommended as a first alternative and treatment Ash @ of 125g as 2nd alternative. Therefore, to enhance sorghum storage life in the North Gondar, storage pests that occur frequently may be managed with Ash @ of 62.5g and 125g as alternative to the currently used insecticides which may cause an adverse effect on the ecosystem. Key words: Eucalyptus wood ash, Maize weevil, Neem and Pepper sorghum storage pest. | en_US |
