“…Other tested plant parts include seeds (Tilahun and Daniel, 2016) powders, and wood ashes (Akob and Ewete, 2007). Tree plants like neem (Ahmad et al, 2015), teak (Rahmat et al, 2019), mahogany (Baba et al, 2020) and cedrela (Okwute, 2012;Tilahun and Daniel, 2016;Gómez-Tah et al, 2020) have also been exploited in pest management to some extent (Regnault-Roger et al, 2012).…”

“…Many experiments conducted on neem, mahogany, cedrela, and teak show that several parts of these plants can be processed and applied as insecticides to control stored produce insect pests (Ahmad et al, 2015;Tilahun and Daniel, 2016;Rahmat et al, 2019;Baba et al, 2020;Gómez-Tah et al, 2020). This study extends the above approaches by evaluating the efficacy of the hardwood extracts of neem, mahogany, teak, and cedrela for the protection of stored maize against infestation by Sitophilus zeamais.…”

Synthetic chemicals continue to play an important role in reducing storage losses attributable to insect pest activities. However, the adverse effects associated with some patented chemicals make synthetic pesticides less attractive and have given the drive to search for alternative methods of pest control. This study evaluated the effects of a traditional gin, akpeteshie crude extracts made of four timber species, neem (Azadirachta indica), mahogany (Khaya senegalensis), teak (Tectona grandis) and cedrela (Cedrela odorata) on the maize weevil Sitophilus zeamais on stored maize grains in the laboratory. Home-made extracts of the test tree plants at concentrations of 0.5, 1.0 and 2% were tested as grain protectants or as insect poisons. All tested extracts in their respective concentrations performed well in the reduction of live insects during maize storage as compared to a non-extract treatment. The mode of action of all the extracts was generally concentration and time-dependent. On average neem extract was the most effective followed by mahogany, teak, and cedrela in that order. Neem and mahogany extracts performed well in reducing grain damage at a concentration of 2% and at 0.5% concentration of cedrela extract respectively. All extracts reduced progeny emergence and acted both as a repellent or a toxicant. The extracts performed better as compared to the untreated control in the viability of maize seeds leading to germination, and subsequent seedling emergence. The relatively low weight loss of the stored grains treated with these crude extracts during the 90-day experimental period at a maximum concentration of 2% is predictive that they can be adopted as safe and alternative grain protectants against weevils in store. The unknown phytochemicals in these akpeteshie hardwood extracts may be responsible for the insecticidal properties against the weevils. For some concentrations of the extracts, germination was inconsistent which led to the suspicion of allelopathy.

Liquid smoke is known to contain compounds that can control plant disease pathogens. This study aims to produce wood-waste liquid smoke and determine its effectiveness as a fungicide on plant pathogens. This research was conducted in two experimental stages, namely: (i) in vitro test as a preliminary test of the effectiveness of teak waste liquid smoke at concentrations of 0, 0.5, 1, 1.5, 2, and 2.5%; and (ii) in vivo test was arranged in randomized block design consisting of seven levels of liquid smoke concentration, namely 0, 1, 2, 3, 4, 5, and 6%, each of which was repeated four times. The results showed that the pyrolysis of 1 kg of wood waste was produced with the proportions of liquid smoke, charcoal and tar, respectively: 312 mL, 31 g, 367 g and the uncondensed gases. Treatment of liquid smoke in the in vivo test showed that a concentration of 1 to 2.5% liquid smoke was able to suppress the growth of the pathogenic fungus Sclerotium rolfsii 100%. The treatment of liquid smoke in the in vivo test showed an effect on inhibition of the growth diameter of fungal colonies, suppressing the disease occurance, and suppressing the lesion diameter.
