सजावटी पत्तेदार पौधे वयस्क तेल ताड़ के बागानों के लिए आदर्श अंत: फसलें Ornamental plants grown for foliage or leaves are called cut foliage plants or greens. Background and shape of the flower arrangements are mainly decided by foliage. Most of the foliage plants are perennial in nature, common ornamental garden/ indoor plants, shade loving and shade tolerant and they can up well under dense shady environments.   Oil palm (Elaeis guineensis Jacq.) is the fasting growing plantation cum oil seed crop which is grown to extent of 4.00lakh ha in the country. It is a perennial crop with a productive life of 30 years and yields about 5 tonnes palm oil per hectare. Grown up oil palm utilizes only 40% area for its growth and production and rest of the area (60%) remains vacant which offers the scope for efficient use of natural resources like space, sun light and aerial environment through inter cropping. However, the major constraint in grown up oil palm plantation is incidence of poor sun light which hardly ranges from18-25% which offers the scope for shade loving crops to some extent. Studies at ICAR-Indian Institute of Oil Palm Research, Pedavegi, Andhra Pradesh revealed that foliage plants like fish tail fern, asparagus, fox tail fern, ti plant, philodendron, dracaena, dumb...

तेल ताड़ के बगीचों में लीफ वेबवर्म, एक्रिया मायरिकी (लेपिडोप्टेरा: डिप्रेसारिडे) के लिए जैव नियंत्रण एजेंट Oil palm, Elaeis guineensis Jacq.(Family: Arecaceae) is the richest source of vegetable oil with high yield levels of more than 5 tonnes of oil per ha per annum compared to other oil seeds crops that give less than 1 ton.  The productivity of the crop is often challenged by water stress, drought, biotic stresses like pests and diseases and constraints related with nutrient management. Since irrigation is given at regular intervals, the micro climate with high humidity is created, which makes congenial conditions for pests and diseases development. It is reported that the oil palms in India are being attacked by a number of insect pests.  In recent years, leaf webworm, Acria meyricki Shashank and Ramamurthy (Lepidoptera: Depressariidae) (Figure 1) is emerging as serious defoliator in many of the oil palm gardens of West Godavari, Krishna and East Godavari districts of Andhra Pradesh, India. However, the infestation is not uniform in those districts which ranged from low to severe form (Figure 2).A yield loss of up to 34 % is reported due to infestation of leaf web worm. The perennial nature of palms and monocropping system as practiced in many locations provide ample opportunities for the build-up of this...
