METHOD AND DEVICE FOR FIGHTING AGAINST BOTRYTIS CINEREA WHILE GROWING GRAFTED GRAPE SEEDLINGS Russian patent published in 2017 - IPC A01G17/02 A01G1/06 

FIELD: agriculture.

SUBSTANCE: method comprises the pre-treatment: blinding stock eyes, preparing graft eyes, inoculation, stratification, treatment of the inoculations against gray rot. Wherein the treatment in the stratification period is carried out with steam containing 0.2% of Albit solution at the temperature of 20-25°C and the air humidity of 90-95%, until the stock eye is developed on 1.5-2 cm. Then the steam temperature is raised to 45-50°C and maintained for 10 minutes. The device comprises a control unit, containers with a substrate, a heating element and a substrate temperature sensor. Wherein the device is made in the form of a film micro-greenhouse with a heating element placed on the bottom under a layer of substrate. In addition, the device comprises two steam generators installed at the right and left ends of the micro-greenhouse and equipped with steam temperature and humidity sensors and a timer. Steam is supplied from the steam generators by means of a pipe with openings and steam reflectors located on the ridge of the micro-greenhouse.

EFFECT: inventions allow increasing the yield of grafted seedlings due to destroying Botrytis cinerea while maintaining the natural balance of beneficial microorganisms and observing biological norms for human protection.
