RESULTS: When assessing the likelihood of growers switching to new crop varieties with improved genetic resistance to disease, the simulation results reveal that adopting these varieties yielded higher net benefit values compared to implementing current fungicide strategies across all rainfall zones. On average, the increase in net benefit varied between 2.6% and 3.5%. Conversely, when we examined the scenario involving modifying the current fungicide strategy, we observed that, on average, switching from the current fungicide management strategy to one which involved additional fungicides was beneficial in about 73% of the cases.
CONCLUSIONS: Our analysis reveals the importance of factors such as commodity prices, production costs, disease-related variables and risk aversion in determining the economic benefits of adopting new crop protection strategies. Furthermore, the research reveals the need for accessible information and reliable data sources when evaluating the benefits of new agricultural technologies. This would assist growers in making informed and sustainable disease management decisions. © 2024 The Author(s).

结果:在评估种植者改用遗传抗病性提高的新作物品种的可能性时,模拟结果表明,与在所有降雨区实施当前的杀菌剂策略相比,采用这些品种产生了更高的净效益值。平均而言,净收益的增幅在2.6%至3.5%之间。相反,当我们检查涉及修改当前杀菌剂策略的情况时,我们观察到,平均而言,在约73%的病例中,从目前的杀菌剂管理策略转向涉及额外杀菌剂的策略是有益的。
结论:我们的分析揭示了商品价格等因素的重要性,生产成本,与疾病相关的变量和风险厌恶在确定采取新的作物保护战略的经济效益。此外,该研究表明,在评估新农业技术的好处时,需要可获得的信息和可靠的数据源。这将有助于种植者做出明智和可持续的疾病管理决策。©2024作者(S)。害虫管理科学由JohnWiley&SonsLtd代表化学工业学会出版。
