Neem in India
MANAGEMENT STRATEGIES
As in case of pests, very limited information is available regarding management of diseases of
neem,and neem oil. Sound silviculturaI practices may be useful in lowering the incidence and spread
of many pathogens. Raising of seedlings in polypots instead of seedbeds helps in checking the
infection of soil borne pathogens. In nurseries where a disease occurs year after year, the use of sick
soil should be avoided. Alternatively, the soil may be fumigated with formalin before use. The
diseased seedlings should be removed to prevent the lateral spread of diseases in nursery. Weeding
should be done regularly as weeds are known to be collateral hosts of many pathogens and act as a
source of infection. In case of seed borne pathogens like Fusarium, Phomopsis and Rhizoctonia
proper site selection for seed production, proper seed storage conditions and exclusion through
quarantines are very important. Other useful measures include selection of date of planting,
maintaining plant population etc.

The use of Paras an (5 g/kg) and Thiram (5 g/kg) as a seed treatment is effective for the control of
damping off. Leaf spotting and blight caused by C. gloeosporioides and A. alternata may be checked
by use of Blitox (0.25%)5. A combined spray of dimethoate (0.02%) with Blitox (0.05%) and Vipul @ 2
mill was found highly effective for the control of major pests and diseases as well as healthy growth of
neem seedlings and young plants.
