Abstract

As vegetable crops are essential for feeding the world's population, significant effort is put into growing environmentally friendly food while also raising production, reducing prices, and improving export potential. In the world, 2.496 million hectares of land are planted with cucumbers, producing 83.8 million tonnes of vegetables yearly. At 65 million tonnes, China is in first place, followed by Iran, Russia, Turkey, and the United States. Vegetable crops are essential for feeding the world's population, which implies their significance in ensuring food security. Additionally, the text mentions that efforts are being made to cultivate ecologically sound produce, increase productivity, and enhance export potential. Results showed that the pest caused a sharp decrease in carbohydrate levels in plant stems and roots, disrupted photosynthesis and metabolism in leaves, and caused changes in leaf shape. Severe damage could result in plant death and reduced yields. The effectiveness of three chemical insecticides, namely Xen pin R, Cruiser, and Viospilan, against aphids was tested. Xen pin R and Cruiser showed high efficacy against aphids, resulting in 94.3-98.2% and 84.4-90.0% yield on the 21st and 14th day, respectively.
