Liriomyza sativae (Diptera: Agromyzidae) is a cosmopolitan, polyphagous pest of horticultural crops and many are resistant to insecticides. Cucumber producers in the Katahari, Biratnagar Eastern region Nepal, have been facing severe challenges recent years due infestations by leafminer. This has emerged as major concern for local cucumber farmers, adversely affecting plant health, yield, economic viability. The objective this study investigate efficacy various insecticides controlling impact these treatments on growth, aspects cultivation. Research plots were sprayed with profenophos + cypermethrin, emamectin, chlorantraniliprole, Btk S. spinosa, spinetoram, azadirachtin, water spray control. Insecticide was monitored examining collected leaf samples leafminer stings, larval mines, larvae number, rate injury. Chlorantraniliprole spinetoram significantly reduced number average larvae, resulting lower injury rates compared insecticide exhibited varying effects height, leaves per plant, male female flower counts, sex ratio. Likewise, chlorantraniliprole application led highest fruit yield. Other also influenced parameters but lesser extent. analysis revealed that had total cost cultivation generated gross return, net benefit-cost Overall, demonstrates most promising results terms control, yield parameters, returns. These findings provide valuable insights farmers can aid developing effective strategies managing leafminers.

Bacillus thuringiensis promotes systemic immunity in tomato, controlling pests and pathogens and promoting yield

Food Security, Journal Year: 2024, Volume and Issue: 16(3), P. 675 - 690

Published: April 27, 2024

Abstract Plant pathogens and pests pose an increasing threat to worldwide food security. To improve strengthen security under increasingly difficult environmental, economic, geopolitical conditions, the prospect of using microbial biocontrol agents becomes desirable. One most studied, commercially used, biopesticide microorganisms is entomopathogenic, gram-positive, soil bacterium Bacillus thuringiensis (Bt). While Bt has been known for many years as insecticidal microorganism used extensively in agriculture, its possible anti-phytopathogen plant growth-promoting activities have received comparatively limited attention thus far. Here, we examine ability promote systemic immunity tomato plants. We investigate how influences disease resistance against several fungal bacterial pathogens, well arthropod pests. In order determine which component (i.e., spores or pure crystals) responsible observed effects on pests, dissected different fractions present a commercial preparation assessed their pest pathogen control. As previously reported literature, our results indicate that proteins produced by are likely primary acting components case however, it appears both directly act such fungus Botrytis cinerea . Spores also induce immunity. Understanding mode action mechanisms will help developing cost-effective safe protection strategies enhancing Taken together, findings suggest could be broad-spectrum management strategies. Pending validation agricultural settings, products market additional uses sustainable growth promotion.
