The present review paper focused on the control of plant diseases by using neem kernel extract. For so many years farmers are extract for pests and in plants Atharvaveda they stated that effectively works diseases. It was controlled seed-borne soil-borne pathogens. early blight wilt tomatoes cowpea. Powdery mildew disease can be Neem has medicinal properties Ayurveda (the ancient book medicine)...

Alternaria radicina Meier, Drechsler & Eddy [syn. Stemphylium radicinum (Meier, Drechsler et Eddy) Neerg.] is a pathogen causing a range of symptoms in carrot, including preand post-emergence dampingoff, necrosis of the crown and root, foliar, flowerand seed-stalks, and umbel and seed blight. The greatest damage occurs post-harvest, during root storage (Meier et al., 1922; Neergaard, 1945; Maud...

Carrot cultivars grown in New York were evaluated for susceptibility to the fungal leaf blight pathogens Alternaria dauci (1999) and Cercospora carotae (2000–03) in an experimental field under continuous carrot cultivation since 1996. Replicated plots were established in a randomized complete block design. Plants were rated for disease incidence and severity at regular intervals. Cultivar susce...

In the past decade Colletotrichum gloeosporioides, C. karstii, and Alternaria alternata represent emerging fungal pathogens on citrus in Mediterranean basin. Selection of tolerant Citrus germplasm offers evaluable long-term solution should be considered as promising alternative to limit synthetic fungicide application manage infections groves. this study, high variability pre-harvest disease sy...

Barnyard grass (Echinochloa spp.) is the most important weeds in rice fields. Some fungal pathogens can potentially be used as biological agents for the control and management of these weeds. For this reason, two pathogenic fungal species were isolated and characterized from naturally infected Echinochloa species. Morphological characters of isolates were studied in order to identify the taxono...

In the present paper introduce an innovative approach to automatically detect and grade the diseases on pomegranate fruit. The diseased pomegranate plant shows specific symptoms colored spots that will occur on the pomegranate fruit. so it is important to monitoring the pomegranate during its growth period and at the time of harvest. The proposed system will be an efficient module that identifi...
