Pepper crops in Guangxi hit by bacterial wilt outbreak!Field trials show 74.28% control efficacy with post-infection application,saving approximately 3,276 RMB in economic losses per mu.

“As vegetables from the South transported North rely on Guangxi, a bumper pepper harvest equals half a year’s work.”As a core production area for national winter and spring vegetables, Guangxi is a major region for pepper cultivation in China. Colored peppers, in particular, have become a key cash crop for increasing local farmers’ incomes due to their good fruit shape, high quality, and stable purchase prices.

However, bacterial wilt—the “top invisible killer” of pepper cultivation—has long been a difficult problem for both growers and plant protection dealers.The disease develops rapidly, spreads aggressively, and is extremely hard to eradicate. The pathogen infects roots through soil, causing plants to wilt and die.In mild cases, yield is reduced by 30%; in severe cases, entire fields are lost.This not only wipes out a year of hard work for farmers but also frequently leaves plant protection dealers facing after-sales disputes and customer loss.

Scientific Diagnosis · Precise Identification of Pathogens

The core of bacterial wilt control lies in identifying the pathogen first, then applying targeted treatments.The Ruitong Biotechnology team strictly follows the standardized workflow:Field Investigation → Laboratory Detection → Customized Exclusive Solution,ensuring precise and effective disease management.

1.Field On-site Investigation for Preliminary Disease Diagnosis

Ruitong Biotechnology technicians arrived at the pepper trial fields in Guangxi promptly.On-site inspection revealed widespread wilting of pepper plants with drooping green leaves.Root examination showed browning at the stem base and discolored vascular bundles, consistent with typical symptoms of bacterial wilt.A preliminary diagnosis was made as pepper bacterial wilt caused by Ralstonia solanacearum.The field had already entered the disease onset stage, with a high risk of further spread.

2.Authoritative Laboratory Testing to Identify the Pathogen

To accurately identify the pathogenic bacterium, technicians from Ruitong Biotechnology collected root and soil samples from diseased pepper plants on-site and sent them to the Ruitong Bio-Research Institute.Using pathogen isolation, culture, and molecular identification techniques, the pathogen was confirmed as Ralstonia solanacearum, with a formal testing report issued.This provided solid scientific support for the development of the subsequent phage-based control program.

3.Customized Exclusive Solution · Standardized Field Application

Based on the field disease conditions and laboratory test report, the Ruitong Biotechnology team customized the “Xiaoqingning+” program for this field, strictly standardizing the application method and water volume to ensure the agents reach the root infection sites directly:

Full-Cycle Field Validation · Verified Control Efficacy

Ruitong Biotechnology team conducted a field trial to evaluate the efficacy of the “Xiaoqingning+” program against bacterial wilt in pepper in experimental fields in Guangxi.

Application dates: December 23, 2025; January 20, 2026; February 4, 2026Investigation dates: January 6, 2026; January 20, 2026; March 6, 2026

Core control efficacy data:

Test Conclusion:Under conditions where bacterial wilt had already occurred and the disease pressure was high in pepper fields, the integrated control efficacy of the “Xiaoqingning+” program against pepper bacterial wilt reached 74.28%.It can effectively suppress the spread of the disease in the field, significantly reduce plant mortality, and achieve stable control of bacterial wilt.

Post-Application Test Report

PART03

14 Days After Application: Pathogens Eliminated, Mildly Diseased Plants Recovered

Field investigation 14 days after application showed that the disease incidence in the treatment group decreased compared with the initial value before application. According to the analysis by the Ruitong Biotechnology team, there are two core reasons for this phenomenon: first, Xiaoqingning achieved 100% precise lysis of Ralstonia solanacearum, significantly reducing the pathogen load in the soil and plants, thus blocking the continuous infection of the disease; second, for the already mildly diseased plants, as the pathogens were eliminated, the wilting symptoms gradually subsided, and the plants recovered to normal growth, resulting in a significant reduction in the number of visually diseased plants in the field. In the same period, the disease plant rate in the control group continued to rise, and the disease had begun to spread in contiguous areas.

74 Days After Application: Stable Disease Control with Significant Growth Differences

Left-side control group: A large number of plants were wilted and died, with yellowing and falling leaves, and rotten, hollow roots. A total of 105 new diseased plants were added in the two replicate plots, and the disease had erupted on a large scale.Right-side treatment group: The pepper plants had dark green leaves and neat growth, with no contiguous plant death. The roots were developed and robust, and only 27 new diseased plants were added in the two replicate plots during the test period.

Calculating the Economic Benefits

Recovered Economic Loss of Approx. 3,276 RMB per Mu

This benefit calculation is based on the average local production level of colored peppers in Guangxi and the average market purchase price during the 2026 season:

• Average Yield per Mature Pepper Plant: 3 kg
• Average On-Field Purchase Price of Colored Peppers in Guangxi (2026 Season): 14 RMB/kg

Key Comparison & Calculation:

• Fewer Diseased Plants in Treatment Group vs. Control Group: 78 plants
• Average Reduced Yield Loss:78 plants × 3 kg/plant = 234 kg
• Average Recovered Economic Loss:234 kg × 14 RMB/kg = 3,276 RMB

Note: Actual returns may vary slightly due to factors such as field management level, climatic conditions, and market price fluctuations.
