Description

Plant disease control composition, plant disease control method, method for reducing chemical damage, pest control composition, pest control method, plant parasitic nematode control composition, and plant parasitic nematode control method

[0001] The present invention relates to a plant disease control composition, a plant disease control method, a method for reducing chemical damage, a pest control composition, a pest control method, a plant parasitic nematode control composition, and a plant parasitic nematode control method.

[0002] Pesticides, such as plant disease control compositions and pest control compositions, are used in agricultural production to control pests and weeds in agricultural crops, thereby reducing the labor required for agricultural work and stabilizing the quality and yield of agricultural products, and are essential for agriculture in ensuring agricultural production. Pesticides include, for example, herbicides for weed control, insecticides for pest control, nematicides for nematode control, fungicides for plant disease control, and plant growth regulators. Among these, insecticides, fungicides, etc. are used as control agents for the purpose of plant disease control and pest control. However, frequent and excessive use of insecticides, fungicides, etc. with the same action against specific plant diseases or pests has become a problem in that insects, plant pathogens, and pests that cause plant diseases become resistant to the insecticides, fungicides, etc.

[0003] Therefore, various studies have been conducted on various plant disease control agents and pest control agents. For example, Patent Documents 1 to 3 describe that saccharin and its salts are useful as plant disease control agents for specific plant diseases. Furthermore, Non-Patent Document 1 describes that saccharin has nematicidal activity against the pine wood nematode, a serious forest pest that causes devastating damage to pine trees.

[0006] However, Patent Documents 1 to 4 disclose that saccharin or a salt thereof is effective against rice blast, cucumber late blight (Botrytis), tomato leaf mold, rice sheath blight, tomato canker, cucumber damping-off, Chinese cabbage soft rot, and rice bacterial diseases (rice bacterial leaf blight, rice leaf sheath browning, etc.). However, its effectiveness against other plant diseases is unclear.

[0007] Furthermore, it is known from Patent Documents 5 and 6 that saccharin or a salt thereof exhibits control and synergistic effects against various pests and pathogenic bacteria when used in combination with the pesticides (diazinon, ethyl demeton, etc.) described in Patent Document 5 or when used in combination with the resistance inducers (flagellin, harpin protein, etc.) described in Patent Document 6. However, it is not clear whether control and synergistic effects are exhibited when used in combination with other insecticides or fungicides.

[0008] It is also known that saccharin or a salt thereof exhibits a phytotoxicity-safeening effect when combined with the herbicide described in Patent Document 7 and with tefuryltrione described in Patent Document 8. However, it is not clear whether saccharin or a salt thereof exhibits a phytotoxicity-safeening effect when combined with other insecticides or fungicides.

[0009] Furthermore, although saccharin or its salts are known to have nematicidal activity against the pinewood nematode (Non-Patent Document 1), it is not clear whether they have a control effect against plant-parasitic nematodes or whether they exhibit a control effect or a synergistic effect when used in combination with commercially available nematicides.

[0010] The present invention aims to provide a novel plant disease control composition and method for controlling plant diseases using saccharin or a salt thereof, a novel method for reducing phytotoxicity using saccharin or a salt thereof, and a novel pest control composition and pest control method using saccharin or a salt thereof.

[0011] The present inventors have discovered a novel plant disease control composition and method for controlling plant diseases using saccharin or a salt thereof, a novel method for reducing phytotoxicity using saccharin or a salt thereof, and a novel pest control composition and pest control method using saccharin or a salt thereof, and have completed the present invention.

Details of the test methods are shown below.

[0417] [Test Example 28] Soybeans (variety: Enrei) were sown and grown until two true leaves had developed. A mixed diluted solution of sodium saccharin and a fungicide diluted with water, a diluted solution of sodium saccharin diluted with water, or a diluted solution of a fungicide diluted with water was sprayed at 2.5 mL per pot to achieve the concentrations shown in Table 30. Two days after spraying, 1.0 x 10 ５ The soybean plants were inoculated by spraying with a suspension of uredospores of soybean rust fungus (Phakopsora pachyrhizi) adjusted to a concentration of uredospores / ml. The plants were then left in an inoculation room at 20°C for 24 hours to promote disease development. Seven days after inoculation, the severity of disease development was examined to evaluate the efficacy.

[0418] The control value was calculated using the following formula for calculating the control value. Then, the presence or absence of a synergistic effect was determined using the Colby formula. The results are shown in Table 30. [Control value] Control value = 100 x (1 - (n / N)) N = disease level in the untreated plot, n = disease level in each plot [Disease level] In the above formula, the following evaluation values ​​were used for N and n. 0: No disease 0.1: Diseased area is about 3% 0.3: Diseased area is about 10% 0.8: Diseased area is about 25% 1.5: Diseased area is about 50% 2: Diseased area is about 70% 3: Diseased area is about 95%

[0419] The synergistic effect was judged using the Colby formula as an index. Hereinafter, in the Colby formula, the theoretical value of the mixture was calculated from the control values ​​of the two active ingredients A and B, and if the actual control value was greater than the theoretical value, it was judged that a synergistic effect existed. Theoretical value = A + B - (A x B / 100): Colby formula A: Control value of active ingredient A at the same concentration as used in the mixture B: Control value of active ingredient B at the same concentration as used in the mixture
