Problems solved by technology

However, the long-term use of copper preparations will not only stimulate the occurrence of mite pests such as spider mite, induce the resistance of bacteria, but also easily cause the copper ion in the fruit to exceed the standard, reducing the quality of the fruit

Abstract

The invention discloses a compound drug for controlling citrus canker, comprising the following components in percentage by weight: 22.5%-30% of allicin, 36%-48% of streptomycin, 6% of wetting diffusant and the balance of kieselguhr filler. The 6% of wetting diffusant consists of 2% of sodium butyl naphthalene sulfonate (NEDALBA-75), 2% of sodium lignin sulfonate (M-9), 1% of lauryl alcohol polyoxyethylene ether (JFC) and 1% of carboxymethylcellulose (CMC). The compound drug for controlling the citrus canker can be used for controlling treetop citrus canker and fruit canker, is the low toxicity and residual free super active biogenic bactericide, has specially good effect on the canker and the control efficiency of more than 80 percent, is safe for fruit tress and is environmentally friendly; and the compound drug has the function of repelling pests spreading the citrus canker and can effectively reduce wounds and cut off propagation paths.

Description

technical field [0001] The invention relates to a compound medicament for preventing and treating citrus canker, belonging to the technical field of pesticides. Background technique [0002] Citrus canker is a bacterial disease caused by Xanthomonas axonopodispv. citri (Hasse) Vauterin et al. The pathogen mainly infects Rutaceae plants, and sweet oranges, navel oranges, limes and other varieties are the most susceptible. It mainly damages citrus leaves, branches, and peels, and causes early fruit drop in severe cases. There are differences in the size of citrus canker lesions of different varieties, and the fruit infected with canker has low nutritional value and poor quality, which not only reduces economic value, but also seriously affects export sales. Citrus canker fungus survives the winter in the lesions of leaves, branches and fruits, and overflows from the diseased parts when the conditions are suitable in the next spring. It is spread by wind and rain and insects, ...
