Agricultural yield is mainly affected by differences in climatic conditions and seasonal diseases. There is a strong need of modern agricultural systems that identify disease in the crops. The goal of this study to design, develop and evaluate GA-SVM based methodology for automatic classification of pomegranate related diseases. This innovative method would be a boon to many and would have lot ...

BACKGROUND AND AIMS Crop protection strategies, based on preventing quantitative crop losses rather than pest outbreaks, are being developed as a promising way to reduce fungicide use. The Bastiaans' model was applied to winter wheat crops (Triticum aestivum) affected by leaf rust (Puccinia triticina) and Septoria tritici blotch (STB; Mycosphaerella graminicola) under a range of crop management...

Southern leaf blight (SLB), gray leaf spot (GLS), and northern leaf blight (NLB) are all important foliar diseases impacting maize production. The objectives of this study were to identify quantitative trait loci (QTL) for resistance to these diseases in a maize recombinant inbred line (RIL) population derived from a cross between maize lines Ki14 and B73, and to evaluate the evidence for the p...

Aloe barbadensis (aloe-vera) also famous as a first aid plant is a valuable natural medicine. Its leaves have parallel venation that contains a soothing thick gel inside it and is useful for treatment and curing of wounds and diseases. In this paper, investigations were carried out to study the effect of dc and ac resistances of the aloe barbadensis leaves. The resistance of the leaf measured s...

OBJECTIVE To investigate the antibacterial activity and phytochemical screening of the aqueous, methanol and petroleum ether leaf extracts of Merremia emarginata (M. emarginata). METHODS The antibacterial activity of leaf extracts of M. emarginata were evaluated by agar well diffusion method against four selected bacterial species. RESULTS The presence of tannins, flavonoids, amino acids, s...

fungi belonging to the mycosphaerella s. l. are widely distributed all over the world. most taxa cause leaf spot diseases, and have considerable impact on cultivation of many economically important crops. on eucalyptus species, for example, mycosphaerella leaf spots are one of the major diseases responsible for severe damage in most parts of the word especially outside of their native cultivati...

Cotton leaf diseases have occurred all over the world including India. They have significant impact on quality and yield of cotton. This paper select bacterial leaf blight, myrothecium and grey mildew as study object. The testing samples of the images are gathered from CICR Nagpur. The image enhancement techniques used include histogram equalization, decorelation stretching, linear contrast str...

The importation of sugarcane varieties from other countries is necessary for the breeding of new varieties suited to the diverse environmental conditions in South Africa. To prevent the introduction and spread of new diseases, it is crucial that any imported pathogens are detected before the cane is released from quarantine. Although not present in South Africa, Grassy Shoot (GS) and Sugarcane ...

Cassia alata Linn is an important medicinal plant as well as ornamental flowering plant. The leaf decoction of Cassia alata has been used to treat infectious diseases in north eastern Nigeria. This study was embarked upon so as to evaluate the safety and efficacy of Cassia alata in the management of fungal infectious diseases. The leaves of the plant were collected, dried and extracted using wa...

Freshwater ecosystems are positioned at low levels in the landscape and receive large inputs of diverse plant-based detritus, a major source of energy for consumers in aquatic ecosystems. We conducted Þeld experiments in Urbana, IL to determine the independent and combined effects of leaves of common tree species including thenorthern redoak (Quercus rubraL.), sugarmaple (Acer saccharumMarshall...
