FAQ

Chilli virus diseases can be managed by Integrated management approaches such as Seeds:

 
  • Soaking of seed in Trisodium citrate solution ( 3-5g per liter) for 15 to 20 min and drying.

 

  • Raising seedlings under Nylon net cover (60-80) mesh

 

  • Soil Application of systemic Insecticides like Furadon @ 1.0 Kg ai / ha at the time of sowing seeds in the nursery bed &

 

  • Prior to transplantation the seedlings should be sprayed with Acephate (1.5 g/liter) or Monocrotophos @ 1.5ml per liter or Dimethoate @ 2.0 ml per liter.

 

b). Main field Management:

 
  • Sowing of border crops like Maize, Bajra / Jowar  15 days before the transplanting of  Tomato/Brinjal/Chilli/onion

 

  • Removal of early infected plants from the field

 

  • Spraying of Acephate @ 1.5g per liter at 7 to 10 days interval 15 days after trans planting until fruit formation  (or) Spraying of Hostothion @ 1.0 ml per liter at 7 to 10 days interval 15 days after transplanting until fruit formation  (or) Imdacloprid @ 0.5ml per liter at 7 to 10 days interval 15 days after transplanting until fruit formation (These chemicals should be alternated with one another and should not  use the same chemical continuously.

 

  • Spraying of Neem seed Kernel extract 2% + sticker at 10 days intervals 15 days after transplanting until fruit formation

 

  • Mulching with silver or black polythene sheet

 

  • Growing of virus tolerant varieties

 

These are assemblies of genotypes or populations representatives of cultivars, genetic stocks and related wild and weedy species.

Papaya ring spot virus in nature is spread  by aphids such asAphis gossypii, A. Cracccivora and Myzus persicae. This virus spreads via aphids within one hour. This virus is not transmitted through seed  but seed quality will be affected due to this virus.

Whitefly, Bemisia tabaci is one of the pests, which develops resistance to pesticides very fast, when same insecticides are sprayed repeatedly. Hence, a management package of spraying dichlorvos 76 EC 1ml/l or deltamethrin 2.8 EC 1m/l against adults, triazophos 40 EC 1.5 ml/l or methomyl 40 SP 1.5 g/l or acephate 75 SP 1 g/l followed by pongamia or neem oil 10ml/l effectively controls this pest. Installation of yellow sticky traps also helps to monitor and to bring down the adult populations.

Okra yellow vein mosaic virus in nature is spread by whitefly insect vector Bemisia tabaci and this virus is not transmitted through the seed.

Treat the tomato seeds with Pseudomonas fluorescence before sowing. Spray the crop with Streptocycline (0.3g/l) 2-3 times at 10 days interval Bacterial wilt resistant tomato varieties can ber grown Crop rotation with maize-sorghum-ragi or maize-onion or garlic-paddy for at least for three years.

Total genetic diversity in a crop gene pool is the result of natural processes unaided by human selection, crop evolution, selection and adaptation in farming systems and formal breeding leading to new genetic combinations.

Treat the brinjal seeds with Pseudomonas fluorescence before slowing Spray the crop with Streptocycline (0.3g/l) 2-3 times at 10 days interval Bacterial wilt resistant brinjal varieties can be grown Crop rotation with maize-sorghum-ragi or maize –onion or garlic paddy for the least for three years.

Genetic resources includes land races, obsolete cultivars, modern cultivars, advanced breeding lines and wild and relatives

They contribute to food security, poverty alleviation, environmental protection and in sustainable development of farming.

A group of living organisms with diverse life forms from microorganism to man, categorized at genes, species and ecosystem levels existing at a give place at a given point of time.

Over 15,000 species of flowering plants are native to this region. These include more than 160 domesticated species of economic importance along with over 320 species of their wild relatives. Diversity occurs for crops like mango, citrus, banana, jackfruit, gooseberry, jamun, wood apple, phalsa, bael, chironji, ber, ginger, turmeric, pepper, cinamon, cardamons, sword bean, velvet bean, gourds, orchids, jasmine, okra, egg plant. The richness of plant biodiversity is largely due to ecological diversity superimposed with tribal and ethinic diversification, plant usages and religious rituals.

It contains basic information from where it is collected, such as soil type, nature of vegetation, altitude, latitude, common name, collectors name etc

Clonally propagated crops are predominantly heterozygous in nature and in many cases seeds are short lived due to recalcitrant nature. Such plants are conserved as living collections in field gene bank. Also conserved for a moderately period in ex situ in vivo conditions. The genetic integrity of clonal genotype is changed through spontaneous mutations and through somaclonal variations during in vitro conservation.
