Many times reddish brown liquid can be seen oozing out from the hole.The hole can be seen on the stem with chewed up fibres protruding out.It occurs round the year but becomes severe after monsoon RED PALM WEEVIL : Rhynchophorus ferrugineus Both the pathogens are mass multiplied by a commercial firm and sold in the market.ģ. Wash face and hands cleanly with soap after spraying.Įntomofungal pathogen Hirsutella thompsonii and Verticillium lecanii are reported to be promising in managing the mites.At the time of spraying, protective mask and clothing should be used.Spraying should be avoided during windy season to prevent contamination.The spray should be applied at the crown region by a climber covering only the top six bunches during non rainy season.Rocker or Pedal sprayer can be used for spraying small trees. The botanicals should be applied in the sequence indicated above at 45 days interval using a one litre hand sprayer.Dilute this 1 litre stock solution by adding 9 litres of water to get 10 litres of 2 % neem oil + garlic emulsion.Mix the garlic extract in the neem oil + soap emulsion.Pour the 500 ml soap solution in 200 ml neem oil slowly and stir vigorously to get a good emulsion.Grind 200 g of garlic and take the extract in 300 ml of water.Slice the bar soap and dissolve in 500 ml lukewarm water.To prepare 10 litres of 2% neem oil + garlic emulsion, 200 ml neem oil, 200 g garlic and 50 g ordinary bar soap are required.Preparation of neem oil + garlic emulsion (2%):.Neem cake application 5 kg per palm per year.Triazophos 40 EC 5 ml/lit or monocrotophos 36 WSC 2 ml / lit or carbosulfan 25 EC 2 ml/ lit in alternation with neem azal 1% 5ml/lit as spot application.Round 2: Neem oil + Teepol (30 ml in one lit. Round 1: Azadirachtin 1% (5 ml in one lit. Spot application of ecofriendly Botanicals TNAU - Agro biocide - 30 ml/tree - (60 days after Carbosulfan root feeding).After root feeding, next harvest should be done 45 days later.Monocrotophos 36 WSC 15ml or triazophos 40 EC ml or carbosulfan 25EC 15 ml / 15 ml of water.Soil application of micro nutrients like, Borax 50 g + gypsum 1.0kg + Manganese sulphate 0.5 kg/palm/ year TNAU Micronutrient solution 200 ml/tree.Įriophyid Mite Management - Chemical Method - Video.* Increased quantity is recommended to increase the plant resistance to the mite. Apply urea 1.3 kg, super phosphate 2.0kg and muriate of potash * 3.5 kg/palm/year.Grow intercrop (sun hemp, four crops/year) and shelter belt with casuarina all round the coconut garden to check further entry.Collect and destroy all the fallen buttons of the affected palm.The life cycle of this mite, which consists of egg, two larval instars and an adult stage, is completed in 7 -10 days. Nymph and Adult is pale in colour with elongate body and worm like appearance.

This mite is very minute in size measuring 200 – 250 micron in length and 36 – 52 micron in width with two pairs of legs. Mite are usually found under the bracts of fertilized female flowers and do not infest the unfertilized flowers. Set up light traps following the first rains in summer and monsoon period to attract and kill the adult beetles.During peak period of population build up, the adult beetle may be extracted from the palm crown using GI hooks.Collect and destroy the various bio-stages of the beetle from the manure pits (breeding ground of the pest) whenever manure is lifted from the pits.Remove and burn all dead coconut trees in the garden (which are likely to serve as breeding ground) to maintain good sanitation.Pupa: Grub pupates in earthen cells at a depth of 0.3 to 1 mĪdult: Adult beetle is stout, brownish black or black and has a long horn projecting dorsally from the head in male. Grub: Grub is stout, sluggish, white “C”-shaped with pale brown head and found at a depth of 5 to 30 cm. Egg: Oval creamy white egg in manure pits or decaying vegetable matter at a depth of 5 to 15 cm.
