Abstract

The invention discloses Streptomyces thioluteus, the preservation number is GDMCC NO: 61327, and the classification name is Streptomycesthioluteus GXMD-hs-43. The strain is simple to screen and easy to cultivate, and the inventor has also established a corresponding cultivation method. Studies have shown that the fermentation broth of GXMD‑hs‑43 strain has a good control effect on citrus green mold, and its inhibitory effect on Penicillium digitorum is as high as 94.81%. In addition, the toxicological experiments of the GXMD‑hs‑43 strain showed that it is a non-toxic microorganism, so it also has the characteristics of good ecological safety, and will not cause secondary pollution during use. The discovery of this strain has enriched the available microbial resources in my country, and its bacteriostatic effect is stable, efficient and environmentally friendly, and it has a good application prospect in the prevention and treatment of citrus green mildew.

Description

technical field

[0001] The invention belongs to the technical field of microorganisms, and in particular relates to Streptomyces sulforabies and its application in preventing and treating citrus green mildew. Background technique

[0002] Citrus green mold is caused by Penicillium digitatum. Citrus green mold can infect citrus through various wounds on citrus. Citrus green mold can survive on various organic substances. When the citrus epidermis has a wound, the conidia of the citrus green mold in the air will attach to the citrus wound and start to infect the fruit. Citrus green mold is a common storage disease of citrus, which often causes citrus fruit to rot and cause serious losses.

[0003] At present, there are three main measures used to control citrus diseases after picking: physical control, chemical control and biological control.

[0004] Chemical control is the most commonly used method to control citrus green mildew at this stage. Chemical control is the use o...
