Abstract

The invention relates to a natural fungicide for controlling citrus scab and a preparation method for the natural fungicide. The natural fungicide mainly consists of the following components in parts by weight: 20-30 parts of salvia officinalis essential oil, 10-20 parts of garlic essential oil, 5-10 parts of myristica fragrans essential oil, 10-20 parts of majoram essential oil, 50-60 parts of tea tree leaf essential oil and 100-200 parts of an organic solvent. According to the natural fungicide disclosed by the invention, the salvia officinalis essential oil with corrosion-resistant and antibacterial effects, and the garlic essential oil are taken as main fungicide components; and the garlic is natural plant broad spectrum antibiotic. The myristica fragrans essential oil, the majoram essential oil and the tea tree leaf essential oil are added as fungicide synergist; by virtue of synergistic effect of the components, the permeability and the durability of pesticide effect are improved; and remarkable inhibiting effect is achieved on elsinoe, sphaceloma, xanthomonas and streptomyces, which cause the citrus scab. According to the natural fungicide, the components are natural plants, and are harmless on environment.

Description

technical field [0001] The invention relates to the field of plant fungicides, in particular to a natural fungicide for preventing and controlling citrus scab and a preparation method thereof. technical background [0002] Scab: Damages young leaves, twigs, and young fruits. Affected leaves begin to show oil-soaked spots, then turn waxy yellow, and the lesions expand, and bulge toward one side into conical tumor grains. If the lesions gather, the leaves will become twisted and deformed, and the fruits will also become deformed fruits, and the leaves and fruits will fall seriously. Spread by wind and rain and insects, the temperature is 16-24°C, and the disease is prone to occur, and the prone period is March to May. [0003] At present, the method of spraying chemical fungicides is mostly used in China to prevent the occurrence of scabs. Long-term use of this chemical fungicides not only brings environmental pollution and poisoning of humans and animals, but with the impro...
