Prevention and treatment of aspergillosis of Ganoderma lucidum

Ganoderma lucidum aspergillosis is the most common disease in the process of Ganoderma lucidum cultivation, caused by Aspergillus fungi, Aspergillus fungi are semi-known fungi subphylum Trichosporales, Aspergillus fungi, many species, more common harm for Aspergillus flavus fungi and Aspergillus niger fungi, let's take a look at Ganoderma lucidum aspergillosis control methods!

Ganoderma lucidum aspergillosis harmful symptoms

Ganoderma lucidum planting substrate contaminated by Aspergillus flavus, colonies were yellow to yellow-green, Aspergillus niger was black, growth spread quickly, absorb nutrients and water, Aspergillus flavus secretion aflatoxin is a strong carcinogen, Aspergillus niger and Aspergillus fumigatus produce high concentrations of spores into the lungs easy to produce aspergillosis or known as "mushroom workers lung disease."

Pathogenesis of Ganoderma lucidum aspergillosis

1. Transmission route: Aspergillus widely exists in soil, air and rotten organic matter, and conidia are transmitted by airflow.

2. Occurrence conditions: Aspergillus mainly uses starch and has the ability to decompose cellulose. Bamboo culture bedstead is easy to produce under the condition of high humidity and poor ventilation. The pH suitable for Aspergillus growth is nearly neutral. Aspergillus niger and Aspergillus flavus can grow at 20~30℃ and 25~30℃, respectively. They can survive for 30 minutes at 45℃.

Control method of Ganoderma lucidum aspergillosis

1, do a good job in the cultivation room, cultivation field and other health work, eliminate pollution sources.

2. The culture medium is strictly sterilized, and sawdust and straw materials need to be stacked or sterilized after exposure.

3. Adding 1× 10-6 Shibaogong or 5×10-6 carbendazim to the mixture can inhibit the growth of Aspergillus flavus and Aspergillus niger.
