Chalkbrood is a mycosis which affects bee brood. The disease occurs in the spring, it worsens in the summer and disappears in the autumn, when the queen stops laying eggs, but reoccurs if fighting measures are not taken in the following spring.

In contaminated apiaries the main treatment with BeeVital Chalk brood is applied twice a year, in the spring and in the autumn, and one can intervene anytime it is considered necessary without the risk of contaminating beekeeping products. BeeVital Chalkbrood is a ‘Bio’ product. Treat the affected brood with a quantity of 20-30ml per colony. The treatment is repeated 2 to 3 times at 7-10 day intervals.
