Management of viral diseases in plants

Plant diseases lead to leaf distortion, leaf wilting, stunted growth and decreased productivity of plants

Various viral, bacterial and Mycoplasma Like Organisms lead to majority of plant diseases.

It leads to approximately 60%reduction in net productivity of crops.

This is crucial in an agricultural based country like India

Viral infections : Resulting in low agricultural yield in India

Most prominent plant diseases are caused by viruses.

Plant viral agents can cause extreme economic losses by reducing seed quality and seed yield.

Yellow Mosaic Virus is one of the most destructive viral disease among various viral disease. It causes major reduction in pulse production in India.

Adverse effects of yellow mosaic virus

Yellow Mosaic Virus leads to yellowing of leaves , stunted growth of plants and reduced flowering .

Reduction in no of pods/plant, seed/plant and seed weight contribute to reduced yield .

An annual loss of 300 million USD is estimated on the basis of rates of incidence of Yellow Mosaic Virus in mungbean, urdbean and soybean (Varma et al, 2005)

It can lead to 100% yield loss if the infection occurs 3 weeks after planting.

Key crops infected by viral diseases

Oilseeds and Pulses ( groundnut, tur and lentils)

Vegetables ( brinjal, lady's finger, chilli, bottle gourd and bitter gourd)

Fruits (Papaya, banana and apple)

Current practices for disease control

• Insects serve as vectors for disease transmission in all plants. These transfer diseases from one plant to another.

• Thus, chemicals like acetphate, cypermethrin and imidachloprid have been used extensively to control the spread of diseases in plants have met little success.

Organica Biotech's technology for managing plant viral disease

Viruses induce undue stress in plants

Beneficial microbes in our formulations improve the health and immunity of plants

These formulations enhance the metabolic pathways of organisms, serve as entry barriers and prevent the growth of unwanted pathogens

These are specifically crafted for soil application and foliar spray application

What is Microbial Input?

A single species/strain or consortium of highly effective

microorganisms including fungi and bacteria

Bacteria Fungi

Single Microbial species

Rhizobium: Forms root nodules,

fixes atmospheric nitrogen

PSB : Solubilizes phosphates in soil making them available

for plant growth

Mycorrhiza : is a symbiotic association composed of a fungus and roots of a vascular

plant
