Smallholder agroecosystems play a key role in the world's food security providing more than 50% of produced globally. These unique face myriad challenges and remain largely unsupported, yet they are thought to be critical resource for feeding projected increasing human population coming years. The new challenge increase production through agricultural intensification shrinking per capita arable lands, dwindling world economies, unpredictable climate change, has led over-dependence on agrochemical inputs that often costly hazardous both animal health environment. To ensure healthy crop approaches, search alternative ecofriendly strategies best fit smallholder systems have been proposed. most common widely accepted solution gained lot interest among researchers farmers is use biological agents; mainly plant growth promoting microorganisms (PGPMs) provide essential agroecosystem services within holistic vision enhancing farm productivity environmental protection. PGPMs roles agroecological cycles fundamental soil nutrient amelioration, improvement, tolerance biotic abiotic stresses, biocontrol pests diseases, water uptake.

As pesticide abuse becomes increasingly serious worldwide, it is necessary to pay attention the biopesticide adoption behavior of agricultural producers. It worth verifying whether cooperatives, as training organizations sharing same social network with farmers, can promote biopesticides through their technology diffusion function. Therefore, based on survey data 837 citrus producers in Sichuan Province, China, IV-probit regression model and a mediation effects were used empirically test impact technical farmers’ addition its mechanism, considering perception variable. The results show that (a) participation significantly enhance probability biopesticides; (b) perceptions biopesticides’ economic health benefits play partial mediating role relationship; (c) has more significant for household higher-educated heads, lower total income, smaller size, relative counterparts. This study provides evidence establishing relevant policy encourage full function cooperatives popularize use biopesticides.

Aphid-Resistant Plant Secondary Metabolites: Types, Insecticidal Mechanisms, and Prospects for Utilization

Plants, Год журнала: 2024, Номер 13(16), С. 2332 - 2332

Опубликована: Авг. 21, 2024

Aphids pose a significant threat to global agricultural crop production, leading widespread pesticide use and resistance. This necessitates the of alternative substances, like plant secondary metabolites (PSMs). Plants have developed protective compounds known as alkaloids, terpenoids, phenolics, sulfur- nitrogen-containing metabolites. These exhibit promising characteristics against aphids, such antifeedant, aphicidal, disrupting survival fitness. review highlights importance application in combating aphid populations. Different insect-resistant substances different mechanisms for managing aphids other pests, including defensive signaling, inhibiting growth, attracting natural predators by releasing herbivore-induced volatiles (HIPV). The biopesticides has proven be an effective, economical, eco-friendly synthetic chemicals. Furthermore, this comprehensively discusses principle role metabolites, encouraging sustainable practices emphasizing integrated management population.

Опубликована: Фев. 1, 2024

There is a general drive to reduce pesticide use owing the potential negative effects of pesticides on environment and human health. The EU Commission, for example, through its "Farm Fork Strategy," has proposed decrease hazardous chemical by 50% 2030. In addition, smallholder farmers in low-income countries do not always follow safety precautions. This necessitates introduction low-risk crop protection strategies also suited these farmers. Agricultural biologicals can substitute for, or at least partially replace pesticides. While market growing quickly industrialized countries, this practice remains limited sub-Saharan Africa. To understand reason behind low adoption biologicals, study examined knowledge, attitudes, practices toward among 150 Chole district Ethiopia. All used and/or inorganic fertilizers protect crops, improve yields, comply with government regulations. was, however, restricted one group bio-fertilizers, which approximately 60% used, no plant was reported. Even though understanding concept deemed high respondents, majority (90%) did identify as safer alternatives conventional agricultural inputs. More than half respondents (54%) recommend their colleagues. Nevertheless, even if responding perceive risk-free, they had positive attitude towards when it came producing healthy food increasing yields incomes. comparison attitude, farmers' knowledge were generally low; thus, efforts are needed create awareness
