The invention belongs to the technical field of
plant protection and particularly relates to a simple and efficient field
inoculation method for a
rice false smut germ. The method comprises the steps: picking
rice false smut balls from rice ears in a rice field at a rice
ripening period in last year,
drying the
rice false smut balls in the air indoors, loading the dried rice false
smut balls into plastic bags or plastic bottles, and placing the plastic bags or plastic bottles ay an indoor shady place; and at a 3-4 stage of young
panicle differentiation of rice, putting the rice false
smut balls preserved in last year into
clean water, carrying out soaking for 3-5 hours, then, carrying out oscillating so as to enable rice false
smut powder on the outside surface of each rice false smut ball to gradually fall off until rice grains are clearly discernible, then, enabling the rice false smut
powder to be completely scattered into water, carrying out filtering with gauze so as to filter off grain residues and other
foreign bodies, then, pouring filter liquor into a
sprayer, adjusting
water volume according to a spraying area, directly spraying the filter liquor to fields at 10 am to 5 pm in a sunny day, and swinging the
sprayer during spraying so as to achieve uniform spraying as far as possible. By adopting the method disclosed by the invention, the onset ear ratio of field artificial
inoculation of rice false smut can reach about 30% and is extremely stable. The method disclosed by the invention is extremely simple and can be used for carrying out field identification on degree of
disease resistance to rice false smut of rice varieties without special utensils and conditions.
