Item Kari Soils are Out of Bounds for Root( Wilt)(1965-05) Pillai, N.G.; Pushpadas, M.V.(1.) Some typical coconut-growing kari tracts of Kerala viz,, Thottappally, Vechoor and Vaikom were surveyed. Comparatively healthy plantations of coconut could be noticed in these areas, and the spread of the root (wilt) disease was, in many instances, seen abruptly to stop at the borders of the kari lands. (2) Stunted growth and poor, per- formance of coconut in highly acid kari tracts could be remedied by proper addition of lime and -superphosphate. (3) Old plantations, especially when neglected,.lost all beneficial properties of kari and became susceptible to root(wilt) disease.Item Kari Soils are Out of Bounds For Root( Wilt)(2007-02) Pillai, N.G.; Pushpadas, M.V.(1.)

A survey of the proximities of the Meenachil, Thodupuzha and Moo-vattupuzha rivers revealed that the infection due to root (wilt) disease of coconut was more on the banks of these rivers and canals leading from them indicating that the river water (and probably the silt carried by it) may be a factor in the spread of the disease. 2. The chemical properties of the river water appear to influence the spread of the disease. The spread of the disease was found to become slow as the river water became more saltish and acidic. 3. It has been observed that most of the wilt diseased palms were severely infected with leaf blight and in many cases with leaf rot. Until definite information about the origin and spread of the disease is available river silt, canal silt, and lake silt should not be allowed to be removed from infected areas to healthy areas; removal and transport of coconut and other plant materials as well as soil from infected to healthy areas should be discouraged and leaf blight and leaf rot, which enhance the damages to the coconut palms should be controlled with Bordeaux mixture spraying.Item Spread Of Root (Wilt) Disease Of Coconut - Some Interesting Observations(1966-06) Pillai, N.G.; Pushpadas, M.V.1.
