Entomopathogens are frequent natural enemies of arthropods worldwide, and they are capable of alternative control agents against the important pests. The optimally selected botanical product can minimize their harmful effect on these entomopathogens, and it becomes essential to know the influence of combinations of botanicals and biopesticides (botanical biopesticide combination (BBC)) in comparison to their sole action. Botanicals, especially neem products, are highly efficient to be combined with the entomopathogens (with some exceptions). There are many possible reasons for the synergistic action of these botanicals, attacking the immune system of the insect being one of the important ones. These botanicals when applied in combination with microbial pesticides showed maximum sublethal effects rather than complete mortality, making them the best alternatives for combating resistance development in insects. To work effectively, biological control agents must be used within a compatible program combined with botanicals. It is highly difficult for such products to compete with chemical controls in high-value crops, so where they can become a commercially viable option in organic cultivation. The increasing acreage is under organic production for high-value export crops, where pesticide residues are undesirable for the environment, and biopesticides and botanicals are good choices for crop protection. Concerning the effect of these products used in pest control, a significant reduction in dosage in relation to the individuals is noticed. By combining the performance and safety, biopesticides and botanicals are efficacious. This knowledge should facilitate the choice of biopesticides compatible with less harmful or naturally occurring botanicals. And if these have to be incorporated into a pest management program through an organic approach, it is necessary to determine the effects of botanicals on the beneficial microbes, on the behavior of pest, the importance of application technique, and the role of application timing for these botanical biopesticide combinations.

植物性生物农药组合概念-有机农业中有害生物管理的可行选择

昆虫病原体是全球节肢动物的常见天敌，它们能够替代控制剂来对抗重要的害虫。最佳选择的植物产品可使它们对这些昆虫病原体的有害作用降至最低，因此了解植物药和生物农药组合（植物性生物农药组合（BBC））与其唯一作用的影响至关重要。植物药，特别是印em产品，与昆虫病原体结合使用非常高效（有一些例外）。这些植物药具有协同作用的可能原因很多，攻击昆虫的免疫系统是重要的原因之一。这些植物药与微生物农药结合使用时，显示出最大的亚致死作用，而不是完全死亡，使它们成为抵抗昆虫抗药性发展的最佳替代品。为了有效发挥作用，必须在与植物药结合使用的兼容程序中使用生物防治剂。这些产品很难与高价值农作物中的化学控制竞争，因此它们可以成为有机种植中商业上可行的选择。高价值出口作物的有机种植面积正在增加，那里的农药残留对环境不利，生物农药和植物药是保护作物的良好选择。关于这些产品在害虫防治中的作用，已注意到与个体有关的剂量明显减少。通过结合性能和安全性，生物农药和植物药是有效的。这些知识应有助于选择与危害较小或天然存在的植物药相容的生物农药。如果必须通过有机方法将其纳入有害生物管理计划，则必须确定植物药对有益微生物的影响，有害生物的行为，施用技术的重要性以及施用时间的作用。这些植物性生物农药的组合。
