The effect of different temperatures on the viability of Metarhizium flavoviride conidia stored in vegetables and mineral oils

The effect of different temperatures on the viability of Metarhizium flavoviride conidia stored in vegetables and mineral oils

Viability of freshly harvested conidia of Metarhizium flavoviride (Gams and Rozypal) stored in mineral, vegetable, or animal oils at 25 degree C was assessed over a period of 4 months. Viability was reduced to below 40% in all but two oils after 4 weeks storage; kerosene, soyabean (Sigma), and peanu...

Zusammenfassung:Viability of freshly harvested conidia of Metarhizium flavoviride (Gams and Rozypal) stored in mineral, vegetable, or animal oils at 25 degree C was assessed over a period of 4 months. Viability was reduced to below 40% in all but two oils after 4 weeks storage; kerosene, soyabean (Sigma), and peanut were the only oils with a conidial viability of over 30% after 6 weeks storage. In a second experiment, storage at 5 and 15 degrees C resulted in enhanced conidial viability of up to 71.9% with kerosene and 92.1% with soyabean after 14 weeks storage
