Ecological farming is increasing worldwide, as more and more consumers prefer chemical-free fruits. As a result, ecological farming is becoming increasingly appealing to European farmers, including those in Romania. However, implementing an effective ecological phytosanitary program remains a challenge for farmers due to limited options and a lack of information about their effectiveness. Romania is a major producer of plums and ranks second in the world after China. Aphids are common pests of plum, and some species are vectors of the damaging , and therefore require special attention regarding their control. Eight ecological products were tested both in the field and laboratory for a duration of three vegetative periods to determine their efficiency in aphid control. The effects of ecological products were compared with five chemical insecticides known to be effective against aphids. Observations were made 24 and 48 h after spraying. Two of the eight ecological products tested were proven to be efficient in aphid control, Ovipron Top and Prev-Am, with a mortality rate over 90%. The results indicate that these two ecological products are comparable in effectiveness to chemical insecticides and could be suitable candidates for both ecological and conventional treatment programs.
随着越来越多的消费者青睐无化学物质的水果，生态农业在全球范围内不断发展。因此，生态农业对包括罗马尼亚农民在内的欧洲农民越来越有吸引力。然而，由于选择有限且缺乏关于其有效性的信息，实施有效的生态植物检疫计划对农民来说仍然是一项挑战。罗马尼亚是李子的主要生产国，产量仅次于中国，位居世界第二。蚜虫是李子的常见害虫，有些种类是有害病毒的传播媒介，因此在防治方面需要特别关注。对八种生态产品在田间和实验室进行了三个生长季的测试，以确定它们对蚜虫的防治效果。将生态产品的效果与五种已知对蚜虫有效的化学杀虫剂进行了比较。在喷洒后24小时和48小时进行观察。测试的八种生态产品中有两种被证明对蚜虫防治有效，即Ovipron Top和Prev-Am，死亡率超过90%。结果表明，这两种生态产品在有效性上与化学杀虫剂相当，可能是生态和传统防治方案的合适选择。
