Surfactin-Containing Compositions for Controlling Scab Disease in Agricultural Products
The present invention relates to a composition for controlling scab disease in agricultural products, which comprises a compound of Formula I or a salt thereof. The present invention further relates to a method for controlling scab disease in agricultural products by using a composition for controlling scab disease, which comprises a compound of Formula I or a salt thereof.
1 . A composition for controlling scab disease in an agricultural product, which comprises a compound of Formula I or a salt thereof:
[Formula 1]
[wherein R is C 11 -C 14 alkyl, and X is selected from Leu, Val or Ile].
2 . The composition according to claim 1 , wherein the compound of Formula I is surfactin.
3 . The composition according to claim 1 , which comprises the compound of Formula I or a salt thereof at a concentration of 1 to 10 mg/kg, as calculated on the basis of free form.
4 . The composition according to claim 3 , wherein the compound of Formula I is surfactin.
5 . The composition according to claim 1 , wherein the scab disease in an agricultural product is potato scab.
6 . The composition according to claim 1 , wherein the scab disease in an agricultural product is scab disease whose pathogen is an actinomycete of the genus Streptomyces.
7 . The composition according to claim 6 , wherein the actinomycete of the genus Streptomyces is Streptomyces turgidiscabies.
8 . The composition according to claim 1 , which further comprises cells of Bacillus subtilis.
9 . The composition according to claim 1 , which further comprises an agricultural material.
10 . The composition according to claim 9 , wherein the agricultural material is zeolite.
11 . The composition according to claim 9 , wherein the agricultural material is an industrial food waste.
12 . The composition according to claim 11 , wherein the industrial food waste is extracted coffee residue and/or extracted tea residue.
13 . A method for controlling scab disease in an agricultural product, which comprises using the composition according to claim 1 .
14 . The method according to claim 13 , wherein the composition is contacted with seed potatoes.
15 . The method according to claim 13 , wherein the composition is sprayed over the plant body.
16 . The method according to claim 13 , wherein the composition is mixed into or sprayed over the soil.
17 . The method according to claim 16 , wherein the compound of Formula I or a salt thereof is mixed into or sprayed over the soil in an amount of 0.01 to 5 mg/m 2 per unit area of soil, as calculated on the basis of free form.
18 . The use of a compound of Formula I or a salt thereof for growth inhibition of an actinomycete of the genus Streptomyces , which is a pathogen of scab disease in an agricultural product including potato.
19 . A method for cultivating an agricultural product, which comprises using the composition according to claim 1 during cultivation of the agricultural product.
