The bioeconomic models developed in Weed Science consider the effect of a species on the crop. Bioeconomic models accounting for species interactions within the weed community might represent more realistic approximation to the economic outcome of weed control options in Mediterranean cereal crops. A bioeconomic model, based in community dynamics, competition and economic submodels, was developed and used to investigate the long-term agronomic, economic and environmental consequences of using herbicide-based strategies for the control of winter wild oats (Avena sterilis) and rigid ryegrass (Lolium rigidum) in winter wheat. The results of simulations indicated that different winner strategies can be postulated depending on selection criterion. Based on purely economic outcome, the best strategy was the application of half-dose herbicide to both species whereas if the goal is to achieve a long-term economically viable and environmental friendly decision making, then the strategy chosen would be the one based on a full-dose herbicide application for the control of L. rigidum and half-dose for control of A. sterilis. The sensitivity of the model to variation in economic and competition parameters was checked. The most sensitive model parameters were the potential yield and the wheat price. Bioeconomic models offer practical guidance regarding the possibilities and limitations of various strategic approaches for weed control.

用于分析强硬黑麦草和不育燕麦亚种控制策略的生物经济模型。冬小麦中的 ludoviciana

Weed Science 中开发的生物经济模型考虑了物种对作物的影响。考虑杂草群落内物种相互作用的生物经济模型可能更接近于地中海谷物作物中杂草控制方案的经济结果。开发了一个基于社区动态、竞争和经济子模型的生物经济模型，用于研究使用基于除草剂的策略控制冬季野燕麦（Avena sterilis）和硬黑麦草的长期农艺、经济和环境后果（黑麦草）在冬小麦中。模拟结果表明，可以根据选择标准假设不同的获胜策略。纯粹基于经济结果，最好的策略是对两个物种应用半剂量除草剂，而如果目标是实现长期经济可行和环境友好的决策，那么所选择的策略将是基于全剂量除草剂应用的策略控制刚性 L. 和半剂量控制 A. sterilis。检查模型对经济和竞争参数变化的敏感性。最敏感的模型参数是潜在产量和小麦价格。生物经济模型提供了关于各种杂草控制战略方法的可能性和局限性的实用指导。那么所选择的策略将是基于全剂量除草剂应用以控制硬蜱和半剂量应用以控制不育杆菌的策略。检查模型对经济和竞争参数变化的敏感性。最敏感的模型参数是潜在产量和小麦价格。生物经济模型提供了关于各种杂草控制战略方法的可能性和局限性的实用指导。那么所选择的策略将是基于全剂量除草剂应用来控制硬蜱和半剂量应用以控制不育杆菌的策略。检查模型对经济和竞争参数变化的敏感性。最敏感的模型参数是潜在产量和小麦价格。生物经济模型提供了关于各种杂草控制战略方法的可能性和局限性的实用指导。
