“…As mentioned for fungicides, some herbicides can also decrease pollen production and viability [50]. Besides that, the indiscriminate application of herbicides can reduce floral community diversity, removes refuges for natural enemies or plants with alternative hosts [106]. Herbicide studies have been traditionally neglected, especially in the case of pre-emergence herbicides, due to its uncommon presence in the exposure methodology proposed by IOBC.…”

Side Effects of Pesticides on the Olive Fruit Fly Parasitoid Psyttalia concolor (Szépligeti): A Review

Pesticide applications in olive orchards could alter the biological control of parasitoid Psyttalia concolor Szépligeti (Hymenoptera: Braconidae) on the key pest Bactrocera oleae Rossi (Diptera: Tephritidae). Psyttalia concolor adults can be contaminated by exposure to spray droplets, contact with treated surfaces or oral uptake from contaminated food sources. Pesticides impact both pest and parasitoid populations when they coexist in time and space, as they reduce pest numbers available for parasitoids and might cause toxic effects to parasitoids from which they need to recover. Therefore, the appropriate timing and application of selective chemical treatments provides the opportunity to incorporate this parasitoid in the IPM of B. oleae. This manuscript reviews the current literature on lethal and sublethal effects of insecticides, fungicides, herbicides, and biopesticides on P. concolor. Insecticides were generally more toxic, particularly organophosphates and pyrethroids, while herbicides and biopesticides had less effects on mortality and reproductive parameters. Some fungicides were quite harmful. Most of the studies were conducted in laboratory conditions, focused on reproduction as the only sublethal effect, exclusively considered the effect of a single pesticide and persistence was hardly explored. Field studies, currently quite scarce, are absolutely needed to satisfactorily assess the impact of pesticides on P. concolor.

“…With this approach, the P output of apple production increased substantially. Reflective transfer films and herbicides should be used in the right manner because they would cause serious environmental impact, such as degraded soil, water pollution by runoff, and leaching [50,51]. However, few works of literature have reported P-related environment footprint induced by reflective transfer films and herbicide use in apple production.…”

Multi-Objective Optimization of Smallholder Apple Production: Lessons from the Bohai Bay Region

et al. 2020

Transforming apple production to one with high yield and economic benefit but low environmental impact by improving P-use efficiency is an essential objective in China. However, the potential for multi-objective improvement for smallholders and the corresponding implications for horticultural practices are not fully appreciated. Survey data collected from 99 apple producers in Quzhou County of Bohai Bay Region were analyzed by the Pareto-based multi-objective optimization method to determine the potential of multi-objective improvement in apple production. With current practices, apple yield was 45 t ha−1, and the economic benefit was nearly 83,000 CNY ha−1 but with as much as 344 kg P ha−1 input mainly from chemical fertilizer and manure. P gray water footprint was up to 27,200 m3 ha−1 due to low P-use efficiency. However, Pareto-optimized production, yield, and economic benefit could be improved by 38% and 111%, respectively. With a concurrent improvement in P-use efficiency, P gray water footprint was reduced by 29%. Multi-objective optimization was achieved with integrated horticultural practices. The study indicated that multi-objective optimization could be achieved at a smallholder scale with realistic changes in integrated horticultural practices. These findings serve to improve the understanding of multi-objective optimization for smallholders, identify possible constraints, and contribute to the development of strategies for sustainable apple production.

“…With the development of modern agriculture, herbicides are increasingly being employed worldwide, accounting for nearly 50% of the adopted agrochemicals [1,2]. Although multiple integrated weed management practices have been encouraged and implemented in crop production, the perceived over-reliance on herbicides has generated concerns among industry, government entities, research scientists and the general public [3,4].…”
