To Control Pest in Coconut

Details
Category	Crop Pest & Disease Management
Crop	Coconut
Crop Family	Arecaceae
Scientific Name	(Cocos nucifera)
Vernacular Name	Nariyeli tree
Scout	HBN
Ingredients	Jaggery, water, cup, stone or a piece of wood, dish and tuber of Agave.
Details of Innovation	Farmer practicing organic farming prepares a paste of jaggery and water to deal with the menace of red palm weevils in the coconut garden. He prepares a paste by boiling two cups of jaggery in one cup of water. After the paste has cooled down, he smears it over the tuber of Agave. This tuber is placed on a stone or a piece of wood in a dish. The dish is filled with a couple of inches of water. Attracted by the jaggery, weevils make a hole in the tuber and stay there for a few days. As a result they can easily be caught and disposed off. One to two such tubers are enough to trap weevils in one hectare of land.

PAS_1	"Alkaloids isolated from Annonasquamosa have shown larvicidal growth-regulating and chemosterilant activities against Anopheles stephensi at concentrations of 50 to 200 ppm. Adults exposed as larvae to different treatments showed reduced fecundity and fertility in females." https://pubmed.ncbi.nlm.nih.gov/8468579/#:~:text=Alkaloids%20isolated%20from%20Annona%20squamosa,fecundity%20and%20fertility%20in%20females
PAS_2	"All plant extracts showed moderate effects after 24 h of exposure; however, the highest toxic effect of bark methanol extract of A. squamosa, leaf ethyl acetate extract of C. indicum and leaf acetone extract of T. procumbens against the larvae of An. subpictus (LC50 = 93.80, 39.98 and 51.57 mg/l) and bark methanol extract of A. squamosa, leaf methanol extract of C. indicum and leaf ethyl acetate extract of T. procumbens against the larvae of Cx. tritaeniorhynchus (LC50 =104.94, 42.29 and 69.16 mg/l) respectively.

Other Community Practices	"Application of neem oil 3%, neem oil 2% + garlic extract 2.5%, NSKE 5%, Fish oil rosin soap 40g/lit were found effective in reducing the mite damage. Significant reduction of mite population and damage was also obtained after spraying with commercial formulations of azadirachtin 1% @ 5ml/lit. of water. But repeated application at regular interval is needed to achieve maximum control." [Aratchige, N.. (2014).
