“…It was also emphasized that studies in the developing countries should be conducted for utilization of botanical extracts for crop protection in the fields as these will be of more worth than bioassays in the laboratories. Previous research showed a promising effectiveness of NSE on H. armigera populations, plant growth, infestation of fruits and effect on yield of tomato, compared to synthetic products or other IPM modules [49][50][51][52][53]. Nevertheless, none of these publications reported chemical standardization of used extracts; hence their findings are not comparable and reproducible and could not reach conclusions.…”

Synthetic insecticides heavily applied to manage agricultural pests are highly hazardous to the environment and non-target organisms. Their overuse through repeated treatments in smallholder farming communities is frequent. Botanical biopesticides are ideal for sustainable pest management in agricultural environments by keeping synthetic insecticide use at a minimum. Here we evaluated a locally prepared neem seed extract (NSE) alongside emamectin benzoate against both lepidopteran pests Helicoverpa armigera (Hübner) and Spodoptera exigua (Hübner) on tomato Lycopersicon esculentum Mill under natural field conditions in Pakistan. We compared pest severity, fruit injury, quality, marketability, and cost:benefit ratio (CBR) between treatments. The concentration of azadirachtin A in the NSE was 26.5 ppm. NSE at 2% (20 mL/L) and the emamectin benzoate at the recommended field rate in Pakistan were sprayed weekly throughout the fruiting stage. The pest larvae were significantly more abundant on fruits than on flowers and leaves. Fruit injury and losses were significantly more important in untreated control compared to NSE and emamectin benzoate treatments. NSE efficacy varied with respect to the cultivars used and the seasons. Cultivar Eden harboured more pests than Adventa, and emamectin benzoate suppressed more pest individuals than NSE. Both the insecticidal treatments were comparable in terms of marketable yield productions as well as unmarketable, uninjured, and recovered fruit yields. NSE generated a higher CBR (1: 9.26) than emamectin benzoate (1: 3.23). NSE suppressed pests by acting as an antifeedant, similar to its synthetic counterpart. Smallholder growers can thus use NSE as a cost-effective solution in tomato pest management in Pakistan.

Sustainable agriculture has become a global priority in response to increasing food demand and the challenges confronting agricultural production, such as biotic and abiotic stresses. In this review, we delve into the role of plant diversity in mitigating these stressors within tomato cultivation. Our investigation reveals that the most extensively studied companion species are Vicia villosa Roth, Coriandrum sativum L., and Allium cepa L., while the primary stressors under scrutiny include nutrient deficiencies, aerial pests, and soil-borne pathogenic diseases. Regarding nutrient deficiencies, the cover crop system has demonstrated its capacity to provide essential nutrients directly and indirectly to plants. In addressing aerial pests and pathogens, all cultivation systems exhibit contributions. Finally, we assert that incorporating plant diversity into agroecosystems can effectively counteract various types of stressors. These benefits align with the application of agroecological principles and the development of sustainable agroecosystems. Further assessments of the effects of additional companion plant species are imperative. This should encompass the identification of their distribution, optimal plant quantities, and cultivation systems that enhance their benefits. Ultimately, these evaluations will aid in the formulation of comprehensive guidelines to facilitate the selection and utilization of plant diversity for long-term sustainability.
