With scarce monsoon rains, agriculture officials in Tiruchi are promoting the use of PPFM bacteria to help crops withstand water scarcity and heat stress.

Key Takeaways

  • PPFM is a beneficial bacteria that acts as a plant growth promoter.
  • It provides short-term drought mitigation for up to 10 days.
  • Recommended dosage is one litre per acre, sprayed twice at 15-day intervals.

In response to the current scarcity of monsoon rains and low water levels in the Cauvery River due to insufficient storage at the Mettur dam, agriculture officials in Tiruchi district have issued a critical advisory. Farmers are being encouraged to spray Pink Pigmented Facultative Methylotrophs (PPFM) to mitigate the impact of drought-like conditions on their crops.

PPFM is a beneficial phyllosphere bacteria that functions as a potent plant growth promoter. According to officials, this biological solution helps crops resist water stress and heat stress for up to 10 days, providing a vital window for survival during dry spells. This is particularly crucial as the El Nino effect continues to weaken monsoon patterns.

Why This Matters

BozokMedia analysis shows that as climate volatility increases, traditional irrigation methods may no longer suffice. Implementing microbial solutions like PPFM offers a sustainable and low-cost buffer for farmers, ensuring that essential crops like sorghum and sugarcane do not perish during sudden water shortages.

The foliar spraying of PPFM during healthy growth stages provides visible and encouraging results in resisting environmental stress.

The practice, promoted by the Tamil Nadu Agricultural University (TNAU), was previously utilized in paddy fields a decade ago. Recently, in the Musiri block, successful results have been observed in crops including sorghum, groundnut, gingelly, and sugarcane. The department plans to distribute PPFM under central subsidized schemes for demonstration plots involving castor and other essential crops.

Historical Background

While PPFM was used selectively in parts of Tamil Nadu during past droughts, it had not gained widespread adoption. However, the current shift in weather patterns has brought this microbial technology back to the forefront of agricultural strategy in South India.

Did You Know?: PPFM is a 'phyllosphere' bacteria, meaning it lives on the surface of leaves and interacts directly with the plant's respiratory processes.

Frequently Asked Questions

Question 1: Which crops can benefit from PPFM spraying?
Answer: It is effective for a wide range of crops, including sorghum, groundnut, gingelly, sugarcane, and ginger.

Question 2: What is the recommended application frequency?
Answer: It should be applied at a rate of one litre per acre, twice with a 15-day interval between sprays.
