Objective: In the present study anti-inflammatory activity of ethanol extract of leaf and bark of Hugonia mystax were inveatigated. Methods: The anti-inflammatory activity of ethanol extracts leaf and bark of H. mystax were evaluated by carrageenan induced rat paw edema to determine its effect on chronic phase of inflammation models in rats. Results: Preliminary phytochemical analysis of ethano...

In this paper we present survey on the various types of leaf diseases in plants and their identification process. An identification problem deals with associating a given input pattern with one of the distinct classes. Plant leaf disease identification is a technique where leaf spot disease is identified based on its different morphological features. There are various successful identification ...

We estimated general and specific combining abilities and examined resistance to northern leaf blight (Exserohilum turcicum) and to gray leaf spot (Cercospora zeae-maydis) in a set of nine inbred popcorn lines. These inbreds were crossed in a complete diallel scheme without reciprocals, which produced 36 F(1) hybrids. Two experiments with a square lattice design and three replications were cond...

This work exposes the automatic computation system to analyse the cotton leaf spot diseases. First to initialize the images from the database (Image features) that are highly related to the test image (new image), where test image is given by the user. Three features are used for matching the train image features in database images, namely color feature variance, shape and texture feature varia...

Lack of physical activity, smoking and/or inappropriate diet can contribute to the increase of oxidative stress, in turn affecting the pathophysiology of cardiovascular diseases. Strong anti-oxidant properties of plant polyphenolic compounds might underlie their cardioprotective activity. This paper reviews recent findings on the anti-oxidant activity of plant leaf extracts and emphasizes their...

Tall fescue (Festuca arundinacea Schreb.) is an open-pollinated, perennial, cool-season turf and forage grass species of great economic importance. The main problems of maintenance of tall fescue, and many other turfgrasses, are two severe fungal diseases: gray leaf spot caused by Magnaporthe grisea, and brown patch caused by Rhizoctonia solani. Three genes from various sources have been introd...

Ginseng root is used more often than other parts such as leaf stem although extracts from ginseng leaf-stem also contain similar active ingredients with pharmacological functions. Ginseng's leaf-stems are more readily available at a lower cost than its root. This article reviews the pharmacological effects of ginseng leaf-stem on some diseases and adverse effects due to excessive consumption. G...

Plant pathologists detect syndromes directly with the naked eye. However, such detection usually requires continuous monitoring, which is time overwhelming and very expensive on large farms. The disease diagnosis is limited by the human’s visual abilities because most of the first symptoms are microscopic. Therefore, seeking rapid, automated, economical, and accurate methods of plant syndrome d...

MilStop fungicide was recently registered for the control of a number of leaf spot and blight diseases, as well as powdery mildew on numerous annual, herbaceous, and woody ornamentals. The active ingredient in MilStop is potassium bicarbonate. MilStop is reported to have curative activity against powdery mildew and is also labeled for the control of diseases caused by fungi such as Alternaria ,...

In the present paper we propose and evaluate a framework for detection and classification of plant leaf/stem diseases using image processing and neural network technique. The images of plant leaves affected by four types of diseases namely early blight, late blight, powdery-mildew and septoria has been considered for study and evaluation of feasibility of the proposed method. The color transfor...
