Spraying of dsRNA molecules derived from Phytophthora infestans, along with nanoclay carriers as a proof of concept for developing novel protection strategy for potato late blight
No full textNot AvailablePhytophthora. infestans is a late blight-causing oomycetes pathogen. It evolves and adapts to the host background and new fungicide molecules rapidly within a few years of their release, most likely due to the predominance of transposable elements in its genome. Frequent applications of fungicides cause environmental concerns. Here we developed to target specific RNA interference-based molecules, along with nano clay carriers, that when sprayed on plants are capable of effectively reducing the late blight infection

disease control strategies. Accordingly, different cultural practices, viz., trap cropping, soil solarization and nonsolanaceous crops were evaluated for the management of potato cyst nematode during summer 2013-14 and 2014-15. Among the potato cultivars used as trap crop, Kufri Jyoti attracted more PCN juveniles and recorded maximum reduction in cyst population than Kufri Swarna. In the succeeding crop Kufri Girdhari, wherein Kufri Jyoti used as trap crop recorded more yield than Kufri Swarna in both the spacings. In the soil solarisation experiment, minimum PCN reproduction factor (Rf) was recorded in soil solarisation followed by application of neem cake (@ 5 t/ha) in combination with Trichoderma viride (@ 5 kg/ha). The same treatment also produced significantly maximum yield during 2013-14 however, during 2014-15 the yield was found to be on par with soil solarisation + carbofuran (2 kg a.i./ha). All the non-solanaceous crops tested reduced the PCN multiplication ratio. Among different non-solanaceous crops, radish recorded 19.6-21.0% reduction in number of cysts and 12.2-16.2% reduction in number of eggs per cyst. Which was followed by garlic, it recorded 15.9-17.7% and 10.3-11.6% reduction in number of cysts and eggs respectively, during 2013-14 and 2014-15. Therefore, the above said treatments either alone or in combination can be used to manage the PCN.Not Availabl
