recently Punjab Agricultural University (PAU), Ludhiana Rice To combat 'Foot Rot' disease in Basmati varieties of 'Biocontrol Agent' “Trichoderma Asperellum” have developed.
'foot rot' disease
- This Bakane disease Also known as.
- it 'Fusarium Verticillioides' Caused by a fungus, which is a soil-seed borne pathogens which through the plant's root spreads infection and ultimately to the base of the stem Affects.
- this especially Basmati rice crop in germinated stage Affects, although in case of transplanting infected plants This infection after transplant Can also cause.
- symptoms: Infected plants first turn pale yellow, then become stunted and dry and eventually (usually) ends Are.
Preventive Management Strategies to Control 'Foot Rot' Disease
- To prevent the spread of disease, farmers adopt the following measures-
- initial germinated seed treatment,
- Trying to use disease free seeds, And
- Destroy infected plants.
- timely seed nursery management
- in the first half of June Sow seeds and transplant in July.
- sowing in may There are often problems in doing so, because the temperature of this month is favorable for the disease.
- Well drained field: The fields where nurseries are being established should be well drained with proper irrigation to avoid the spread of 'foot rot' disease.
- current practices
- before sowing and transplanting seeds To 'Trichoderma harzianum' Is treated with.
- seeds before sowing 'Sprint 75 WS' (Carbendazim + Mancozeb) As from fungicides is also treated.
- but this chemical treatment are, which harmful to soil are and Toxic to rice consumers Can happen.
Importance of new biocontrol agent 'Trichoderma asperellum'
- This is rice Agricultural technology This is an important development that will offer a more sustainable strategy, providing a non-chemical alternative to traditional pesticides.
- This change is for food security Ensuring safe rice production in line with global standards Does.
- it reduce environmental damage doing to aid in disease management Will help.
