This spraying regime is to continue until the end of August. Unfortunately, continuous use of copper-based bactericides lead to a buildup of copper in soil and can be related to yield loss in walnut orchards. A natural antibiotic produced by a strain of Streptomyces by the name of kasumin or kasugamycin has been found to have high efficacy against Xanthomonas arboricola pv.
A continuous spraying schedule is set to conclude by the end of August. However, prolonged use of copper-based pesticides can lead to copper accumulation in soil and may contribute to yield reduction in walnut groves. A naturally produced antibiotic from Streptomyces, referred to as kasumin or kasugamycin, has been discovered to exhibit high efficacy against Xanthomonas arboricola pv.
