“…The presented outcomes showed a remarkable rising in the activity of ALT in animals treated with AcF compared with the control group. Nevertheless, this rising is considered to be within the normal ALT range of up to 45 IU/L as reported by Derbalah et al [ 62 ]. This shows an agreement with other studies [ 54 , 63 ].…”

Eichhornia crassipes were evaluated in order to investigate the insecticidal activity towards Aphis craccivora adults. The LC50 values were promising and reflected the bio-efficacy of the tested extracts (39 and 42 mg/L), respectively, and reduced the fecundity markedly. Using GC/MS analysis, the major components were n-hexadecanoic, linolenic, hexadecenoic, myristic, stearic acids, linolelaidic acid, methyl ester and some terpenoids, alkaloids, and hydrocarbons. A safety assessment of non-target organisms is essential for the development of new pesticides. In order to guide the rational use of the most potential insecticidal extracts AcF and EtF, the effect of these extracts on body weight, hematological indices, biochemical indicators, and histopathology of some relevant organs of albino rats (as a model for mammals) was investigated. The research outcomes revealed that the LC50 of AcF and EtF extracts had gradually raised body weight for 14 days (p > 0.05). Similarly, there were no remarkable alternations in the complete blood count (CBC); only a slight decrease in the monocytes count (612 ± 159.80 × 103 µL) in the EtF-treated group. There was a notable increase in alanine transferase (ALT) activity (36.73 ± 1.44 IU/L) in the AcF-treated group. No destructive changes were noted with the remaining biochemical parameters. Cholesterol and triglycerides non-significantly increased in the EtF group, whereas, cholesterol levels decreased significantly in the AcF group. In addition, histopathological examination reflected minor changes in AcF and EtF groups in the form of mild inflammation in the lungs and mild vacuolar degeneration in the kidneys, while no lesions were detected in the heart and liver in the same groups. Thus, the present research suggested that AcF and EtF extracts of E. crassipes are safe green insecticides for insect control strategies.

“…Finally, despite the ineffectiveness of melaleuca essential oil in the treatment of cowpea been seed, this oil may be useful in the treatment of other seeds and other pathogens. Essential oils present a low risk to the environment, producers and consumers, and hinder the development of pathogen resistance [50]. Thus, further studies on the use of these oils in the management of plant pathogens are needed to make them a viable alternative for farmers.…”

Aims: This study aimed to evaluate the fungitoxic potential of melaleuca essential oil on the mycelial growth of Alternaria alternata under in vitro condition and the treatment of cowpea beans. Study Design: The experiments comprised completely randomized designs: Eleven treatments with five replicates on in vitro test; and six treatments with five replicates on in vivo test. Place and Duration of Study: The work was carried out at the Center for Agrifood Science and Technology of the Federal University of Campina Grande, Pombal, Brazil, since February 2018 to February 2019. Methodology: In the in vitro experiment, the essential oil was incorporated into the culture medium and poured into Petri dishes. The treatments consisted of different concentrations of the essential oil (0.0125, 0.025, 0.05, 0.1, 0.2, 0.25, 0.50, 0.75, and 1.0%), a negative control (0.0%), and a positive control (Thiram). Discs of culture medium with fungal mycelia were inoculated in the center of the plates and incubated for seven days at 27±2ºC. The percentage of mycelial growth inhibition (PGI) and the index of mycelial growth speed (IMGS) was calculated to verify the difference between treatments. In the in vivo experiment, the bean seeds were treated with different concentrations of EO (0.0, 0.2, 0.5, 1.0, and 5.0%), a negative control (0.0%), and positive control (Thiram). Seeds were inoculated with colonies of the fungus for 48 hours, and after that, we performed the seed sanity test. Results: Under in vitro conditions, all concentrations of melaleuca essential oil reduced the mycelial growth of A. alternata. The oil reached complete inhibition of fungal growth from 0.2% concentration and above. In the cowpea treatment, the essential oil had no significant control over the percentage of infected seeds. Conclusion: The melaleuca essential oil had a fungitoxic effect on the A. alternata under in vitro conditions. However, using the adopted methodology, on the cowpea bean seed treatment, the essential oil did not reduce the incidence of A. alternata.

“…The current result confirmed that dursban is also highly effective in the management of termites on hot pepper seedling beds beside its effectiveness on the management of wood destroying termites (Roll, 2007). Several other authors also stated that botanicals like Calotropis procera, Ipomoea fistulosa, Maesa lanceolata, Croton macrostachyus, Tegetes minuta, Datura stramonium and Azadirachta indica were reportedly used for the management of termites throughout the world (Derbalah et al, 2012;Singha et al, 2013;Upadhyay, 2013).…”

“…There are also many plant-based botanicals that could act against termites in crop fields and vegetations. The latex and quinines of some botanicals like Calotropis procera, Ipomoea fistulosa, Maesa lanceolata, Croton macrostachyus, Tegetes minuta, Datura stramonium and Azadirachta indica are reportedly used for the management of termites throughout the world (Derbalah et al, 2012;Singha et al, 2013;Upadhyay, 2013). The use of indigenous plant extracts as an alternative for insect pest control also reported (Abdullahi et al, 2011;Sathyaseelan et al, 2008).…”
