Botrytis cinerea is a semi-known fungi, the main infection of inflorescences and fruits, of which the inflorescence victims most. It has been observed that grape gray mold disease has two obvious period of onset, one flowering, the second is the fruit coloring period. The severity of illness and air humidity, growth potential and wounds are closely related. Wet or rainy weather, serious disease occurs, the air is susceptible to light when dry; weak growth of the disease is very heavy, strong growth of light; removal of the secondary tip timely incidence of light, remove the vice
