When coffee leaves are infested, leaf spots can appear on both sides. The spots are subrounded, brown at the edges and grayish-white in the middle and reddish-brown in seedling leaf spots. As the spot expands, the spot appears in concentric whorls and has a distinct edge. When berries are infected, they produce suborbicular fruit spots, and as the spots expand, they can cover the entire fruit, resulting in necrosis and loss of the berries.

Lifeasible is committed to plant science research and has many years of experience in coffee disease control services. Based on advanced biotechnology and in-depth knowledge, we aim to provide effective solutions for coffee brown eye spot control and promote the sustainable development of the coffee industry.

Coffee brown eye spot damage and control significance

Coffee brown eye spot mainly affects the leaves and berries of young seedlings, young trees, or coffee plants with weak resistance to the disease. The leaves of coffee nurseries and newly planted seedlings are most susceptible to the disease, while adult coffee leaves and berries can be susceptible to the disease. Under suitable conditions, the disease spreads rapidly, leading to massive defoliation of the coffee plant. This results in severely weakening the tree, impairing the photosynthesis of the plant, and reducing quality, resulting in extremely serious yield losses. At the same time, coffee brown eye spot disease will cause the susceptible berries to cling to the seed shell, resulting in difficulties in hulling and affecting coffee quality. Effective prevention and control of coffee brown eye spots can promote the growth and fruiting of coffee trees, significantly improve the quality of coffee, and obtain significant economic benefits.

Methods of coffee brown spot prevention and control

In addition to conventional methods of cultivation condition management and chemical control, we offer biological control and identification of coffee brown spot pathogens. These are effective at preventing and controlling coffee brown rust spots.

• Biological control

Our Bacillus strains (B1171, TWC2, BS2C, and GT2) control coffee brown spot pathogens effectively, with inhibition rates reaching more than 50%.

• Identification of the causal agent of the coffee brown eye spot

The pathogenic bacteria of the coffee brown spot were identified by isolating and culturing the bacteria and determining their pathogenicity, as well as using morphological and molecular analyses. We were also able to analyze the occurrence of coffee brown spot disease in the field and research the resistance of varieties to the disease. We analyze the strains obtained by purificatiofromon the pathogenic samples using rDNA-ITS clone sequencing and combine the sequencing results with morphological characteristics to identify the causal agent of coffee brown spot effectively. Using this service, we can identify coffee brown spot resistant or immune varieties and determine the level of resistance to the disease.
