In, branches, the disease can efficiently be controlled by, cutting off the infected part and protecting the cut with a, fungicidal paste. Major fungi in maize included Fusarium moniliforme (present in 97% of samples), Aspergillus flavus (85%), Penicillium citrinum (67%), Aspergillus niger (64%), Lasiodiplodia theobromae (58%) and Fusarium semitectum (45%). Physiological studies of fungi complexes associated with cashew diseases. Control measures other than direct chemical attack on the viral pathogen must be attempted. Aflatoxins were not detected by quantitative high performance thin layer chromatography. Join ResearchGate to find the people and research you need to help your work. The disease is controlled by spraying with fungicides like Miltox and Copranol but the frequency of application required for good control is too high and uneconomic. behaviour are still unknown. The processed kernels are the principal com-, modity exported to the USA, Europe and Japan, Pessoa et al., 1995). A resinose do cajueiro (The cashew gummosis). Cashew is an extremely important source of income for thousands of people in the Brazilian Northeastern—in growing the plant, in harvesting the nuts, in processing the kernels and apples, and in marketing the products. Helminthol. Ilh, Cardoso, J.E., Cavalcanti, J.J.V., Cavalcante, M.J.B., Arag, Felipe, E.M., 1999. Apparently no damage to, production has been recorded in Brazil. Adults are medium in size, dark brown in colour and measure … Obtain and identify metabolites of endophytic fungi and common plants in the Northeastern Brazil, which have antioxidant, antiacetylcholinesteric, antileishmanial and / or antifungal action. Thus, the present study mapped the potentiality of applications of the various parts of the cashew, which allows adding value to the cashew agribusiness. In older plants the disease may take, several months before the first symptoms can be, detected. Nuts and oilseeds, Mycoflora and mycotoxins of Brazilian cashew kernels, Evaluation of biological activities of caatinga fungi and vegetable secondary metabolysts, Effect of soil and climatic conditions in occurrence of cashew gummosis, INTERAÇÃO DAS CONDIÇÕES EDAFOCLIMÁTICAS COM A RESINOSE DO CAJUEIRO, Powdery mildew damage to the production of BRS 189 cashew plants. Bras. isolates and resistance of cashew (, L.) to the pathogen. We use cookies to help provide and enhance our service and tailor content and ads. powdery mildew). Menezes, M., Karan, M.Q., Moura, M.C., 1975b. Instituto de Micologia, Publica. Em mudas de cajueiro e mangueira no. of cashew kernel). Anthracnose is by far the most important disease. Despite the economic viability of this crop, there are constraints to its production which also compromise the yield. 2011. The taxonomic position of the pathogen, has been discussed by Freire (1998). Aspergillus flavus (86% of samples) was again dominant in copra, with Rhizopus oryzae (52%), Aspergillus niger (43%), Eurotium chevalieri (43%) the only other species exceeding 40% infection. Tel. Weekly, simultaneously attack the seedling leaves, increasing, the severity of the anthracnose. All rights reserved. of cashew and mango in the Ceara State). not used. Major diseases of mango and their control measures are discussed below. severity of powdery mildew was recorded in the genotype In due course, the bark splits and peels off and the affected shoots starts drying up from the tip. Later, the foliage becomes bunchy with much reduced sized of leaves. was first recorded by Ponte et al. Rep. 62 (5), 416–420. occurrence), 3 ( generalised occurrence) and 4 (generalised high-severity occurrence). Competi, fungicidas no controle da antracnose do cajueiro (. Osservazioni preliminari su. Proceedings of the 11th Annual Meeting of the Brazilian. Ocorr. Powdery mildew, caused by the fungus Pseudoidium anacardii, is currently the most important cashew disease, affecting leaves, inflorescences, and fruits. Spraying tall cashew trees is not an easy, task. Imunidade do cajueiro, Ponte, J.J., Nobre, R.H.P., Nascimento, M.L.R., 1975. Protect the cut surfaces by applying Bordeaux paste. It was found that the best treatment for disease control and plant production was the trifloxystrobin and tebuconazole fungicide. For the chemical treatment without scraping, Nativo® fungicide is efficient through direct application. The data were submitted to the Doornik- A. flavus was the next most frequently isolated species. Rev. Diseases have been reported to cause significant cashew yield loss in Brazil, a major cashew-producing country. were detected in cashew kernels (Andrade et al., 1990). The treatments were replicated four times. Proceedings of the International Cashew and. In light of this research, small scale chili farmers will be able to lessen pesticide treadmill thereby escalating ecological safety and profitability. Nematode attack has so far not been detected in this crop. Cardoso, A.A. dos Santos, F.M.P. Chapter 1. Studies conducted in, Brazil have demonstrated that fungi associated with, kernel infection are endophytic to cashew plants or can, invade ovaries through flowers or be introduced into the, young kernels by insects (Freire, 1999). Cashew Fusarium Wilt Disease (CFWD) is currently a serious devastating disease of cashew (Anacardium occidentale L.), ... and timely planning for initiation of control measures. In India, the, rot in immature and mature nuts was confirmed by, Nambiar (1978). On leaves of adult, plants or on mature leaves of older seedlings lesions are, black, angular in shape, with a chlorotic halo, which can, usually reach twice the lesion size. Samples of major commodities were obtained from farmers' stocks and middlemen in major producing areas throughout the country. Multimycotoxin analysis by tlc and hplc were positive for mycotoxins and other secondary metabolites particularly from the infected samples. Gmelina arborea. Dc.). Cashew diseased samples of leaves, stem, inflorescences, twigs, flowers, nuts and apples showing symptoms (e. g. small, water-soaked, circular or irregular yellow, dark or brown spots or lesions on leaves, fruits and flowers, sunken surface, especially on the apples, blight, gum exudates) were collected for isolation of presumptive causative organism.
