Abstract

The nematicidal activity of acetyl salicylic acid (ASA) was investigated against root-knot nematode (Meloidogyne incognita ) under laboratory and greenhouse conditions. The results of the laboratory experiment showed that ASA exhibited nematicdal activity against 2 nd stage juveniles of nematode with a LC 50 value of 150.43 ppm. In the greenhouse experiment, the effect of ASA at three concentrations was tested against root-knot nematode on tomato plants in comparison with oxamyl nematicide as standard treatment. All plants were examined to assess disease severity based on the number of galls per root, egg masses per root, developmental stage within the root system, and average of eggs number per egg mass as well as plant growth characteristics were estimated. The results showed that all tested treatments reduced tomato root galling significantly compared with the untreated treatment. The numbers of galls/root system were (6.33, 12.67, 18.67, and 28.67) for the treatments of oxamyl and 300, 200 and 100 ppm of ASA, respectively, compared with the untreated check (113) and the other parameter were in the same trend. All treatments increased shoot and root weights and lengths compared with the untreated check. In conclusion, ASA has nematicidal activity to suppress root-knot nematode infection in tomato plants. Thus, this approach could be a safe alternative to use chemical nematicides for the management of plant-parasitic nematodes.
乙酰水杨酸对番茄根结线虫的杀线虫活性研究。
研究了乙酰水杨酸(ASA)对根结线虫(Meloidogyne incognita)的杀线虫活性。室内实验结果表明,ASA对线虫2期幼虫具有向列线虫活性,其LC 50值为150.43 ppm。在温室试验中,比较了三种浓度ASA对番茄根结线虫的防治效果,并与标准处理恶氨酰杀线虫剂进行了比较。根据每根虫瘿数、每根卵团数、根系发育阶段、每卵团平均卵数以及植物生长特征对所有植株进行检查,以评估疾病严重程度。结果表明,与未处理相比,所有处理均显著减少了番茄根瘤病的发生。与未处理(113)相比,oxamyl处理和300、200和100 ppm ASA处理的根瘤数分别为6.33、12.67、18.67和28.67个,其他参数的变化趋势相同。与未经处理的对照相比,所有处理均增加了茎和根的重量和长度。综上所述,ASA具有抑制番茄根结线虫侵染的杀线虫活性。因此,这种方法可以作为化学杀线虫剂管理植物寄生线虫的安全替代方法。
