Use of chemical pesticides for controlling viral disease in different crops leads to the development of various problems, viz. residue in sprayed crop, pest resistance, pest resurgence and environmental pollution. It was necessary to find some products that were environmentally safe. So, during this study, biostimulants, viz. buttermilk, kaolin, vegetable oil, neem oil, horticultural mineral oil and lemon grass oil, were tested at different concentrations for the management of viral diseases in muskmelon. Among these biostimulants, spray of buttermilk at 20% concentration was found to be highly effective with minimum % disease incidence (50.8%) and % disease severity (21.3%), followed by kaolin 2%. Other treatments were also found to be significantly effective in the management of viral disease than the control. In addition to disease control, buttermilk at 20% was also found to increase number of fruits per plant (2.2), number of marketable fruits per plant (2.2), fruit weight (983.3 g), chlorophyll content (26.91 mg m−2) and photosynthetic activity (43.80 mg m−2). Similar to buttermilk 20%, kaolin 2% has also been observed to have significant effect on all abovementioned traits. As buttermilk 20% spray was found to increase growth and yield of sprayed plant along with controlling viral disease, it can act as a good alternative for the pesticide spray in future because spray of pesticide majority time leads to residue problem, pest resistance and pest resurgence problem.

生物刺激素是杀虫剂的重要非化学替代品，用于管理甜瓜病毒病

使用化学农药来控制不同作物的病毒病会导致各种问题的发展，即。农药残留、病虫害抗性、病虫害死灰复燃和环境污染。有必要找到一些对环境安全的产品。因此，在这项研究中，生物刺激素，即。对不同浓度的酪乳、高岭土、植物油、印楝油、园艺矿物油和柠檬草油进行了测试，以控制甜瓜中的病毒性疾病。在这些生物刺激剂中，发现浓度为 20% 的酪乳喷雾非常有效，发病率 (50.8%) 和疾病严重程度 (21.3%) 最低，其次是 2% 的高岭土。还发现其他治疗在病毒性疾病的管理中比对照显着有效。除了疾病控制，还发现 20% 的酪乳可增加每株植物的果实数量 (2.2)、每株可销售的果实数量 (2.2)、果实重量 (983.3 g)、叶绿素含量 (26.91 mg m-2) 和光合活性 (43.80 mg m-2)。与 20% 酪乳相似，2% 高岭土也被观察到对上述所有性状都有显着影响。由于发现 20% 的酪乳喷雾剂可以增加喷雾植物的生长和产量，同时控制病毒病害，它可以作为未来农药喷雾剂的良好替代品，因为农药大部分时间喷洒会导致残留问题、害虫抗性和害虫死灰复燃问题。80 毫克 m−2)。与 20% 酪乳相似，2% 高岭土也被观察到对上述所有性状都有显着影响。由于发现 20% 的酪乳喷雾剂可以增加喷雾植物的生长和产量，同时控制病毒病害，它可以作为未来农药喷雾剂的良好替代品，因为农药大部分时间喷洒会导致残留问题、害虫抗性和害虫死灰复燃问题。80 毫克 m−2)。与 20% 酪乳相似，2% 高岭土也被观察到对上述所有性状都有显着影响。由于发现 20% 的酪乳喷雾剂可以增加喷雾植物的生长和产量，同时控制病毒病害，它可以作为未来农药喷雾剂的良好替代品，因为农药大部分时间喷洒会导致残留问题、害虫抗性和害虫死灰复燃问题。
