 दलहनी फसल अरहर में एकीकृत रोग प्रबंधन Pigeon pea is an important pulse crop and has major role in food and nutritional security because it is a rich source of protein, minerals and vitamins. The cultivated area and production of pigeonpea have recorded a steady positive growth in the past 50 years, but the mean national productivity has remained unchanged at around 700 kg/ha. To increase its productivity, breeders are trying to develop suitable varieties with subjective spread, growth, duration, disease and pest resistance under varied agro-climatic growing conditions.  Diseases are a continual problem and control measures must be planned for developing sustained production. Each condition that affects plant growth also affects the disease causing organism and the effectiveness of any control measure. In general, conditions that favour rapid, lush plant growth also favor disease development. No single control method is effective in every disease situation. Often a complex of disease interactions defies simple explanations or solutions. Thus to overcome these constraints Integrated disease management (IDM) has been developed for pigeonpea diseases. “Integrated disease management (IDM) involves reducing losses due to diseases to tolerable levels, allowing agriculture to remain productive and profitable while minimizing health and environmental risks. IDM contributes to long-term sustainability by combining the judicious use of management tools”. Integrated disease management for pigeonpea diseases includes...

अरहर के मुख्‍य रोगों तथा कीटों का एकीकृत प्रबंधन Pigeonpea (Cajanus cajan (L.) Millsp.) is one of the most important legume crops of India. It is known as red gram, arhar and tur in the country. It is an important source of proteins (22%) along with carbohydrates, fibre, certain minerals viz., iron, calcium, magnesium, zinc, iodine, potassium and Phosphorous and ‘B’ complex vitamins.  Pigeonpea stalks are also a major source of firewood and live stock feed. India is the world’s largest producer and consumer of pulses including pigeonpea. About 90% of the global pigeonpea area is in India contributing to 93% of the global production. It occupies 4.9 m ha area with 3.1 mt production which accounts for a productivity of 1145 kg/ha; ranking ninth in the world. Kharif is the main growing season of pigeonpea in India and major pigeonpea growing states are Maharashtra, Uttar Pradesh, Madhya Pradesh, Karnataka, Gujarat, Andhra Pradesh, Tamil Nadu, Bihar and Chhattisgarh. Cultivation of pigeonpea on bunds in low land areas is becoming popular and profitable among the farmers. Traditional varieties of pigeonpea need about 6 to 9 months to mature, while the improved varieties developed can be harvested in 3-4 months. Both long duration (180 days) and medium duration (130-140 days) genotypes are grown in...

अरहर या तूर फसल के 6 प्रमुख कीट पतंग और उनके प्रबंधन Pigeon pea (Cajanus cajan L.,) is an important legume crop belonging to the Fabaceae family. In India, it is mostly cultivated during rainy (kharif) season as sole or intercrop for green vegetable and dry seed purpose. Major pigeon pea growing states of our country are Maharashtra, Uttar Pradesh, Madhya Pradesh, Karnataka, Gujarat, Andhra Pradesh, Tamil Nadu and Bihar. Among the various constraints limiting Pigeon pea production, insect pests are the major ones. The important insect’s pests’ causes’ economic loss by attacking the crop at vegetative and reproductive stage are Pod borer, Helicoverpa armigera, Legume pod borer, Maruca testulalis, Pod fly, Melanagromyza spp, Blister beetle, Mylabris spp. Pod bug, Clavigralla spp, Plume moth, Exelastis atomosa and Blue butterflies.  Details of these insect pests are as follows:  1. Pod borer, Helicoverpa armigera Hubner (Noctuidae; Lepidoptera) It is the important insect pest of chick pea and it damage sometimes cause ≥ than 80 % of crop yield loss. Young larvae feed voraciously on the developing buds, flowers while matured larvae bore into the pods and feed the grains (Fig.1). Adult moth has a V-shaped speck on the light brownish forewings and a dark border on the hind wings. It lays the spherical yellowish eggs singly...
