Pest control composition
View Patent ↗Disclosed is a pest control composition comprising at least one pyripyropene derivative of formula (I) or agriculturally and horticulturally acceptable salt thereof and at least one other pest control agent as active ingredients. The combined use of the two ingredients can provide a better insecticidal effect.

R 1 represents hydroxyl,
R 2 and R 3 each represent —OCO-c-C 3 H 5 , and R 4 represents hydroxyl, and
wherein the other pest control agent is selected from the group consisting of acetamiprid, imidacloprid, and a compound of formula (II):
wherein R 101 represents methoxycarbonyl, R 102 represents methyl, R 103 represents ethyl, X 101 , Y 101 , Y 102 , Y 104 and Y 105 represent a hydrogen atom, X 102 represents methyl, and Y 103 represents OCF 3 or OCF 2 CHF 2 , and
wherein the pest control composition comprises 0.1 to 80% by weight of the at least one pyripyropene derivative of formula (I) or agriculturally and horticulturally acceptable salt thereof and 0.1 to 80% by weight of the at least one other pest control agent.
2. The composition according to claim 1 , which further comprises an agriculturally and horticulturally acceptable carrier.
3. The composition according to claim 1 , which is a wettable powder comprising 0.1 to 80% by weight of the pyripyropene derivative of formula (I), 0.1 to 80% by weight of the other pest control agent selected from the group consisting of acetamiprid, imidacloprid and a compound of formula (II), 0.6 to 30% by weight of a wetting agent and a dispersant, and 20 to 95% by weight of an extender.
4. The composition according to claim 1 , which is a water dispersible granule comprising 0.1 to 80% by weight of the pyripyropene derivative of formula (I), 0.1 to 80% by weight of the other pest control agent selected from the group consisting of acetamiprid, imidacloprid and a compound of formula (II), 0.6 to 30% by weight of a wetting agent, a dispersant, and a binder, and 20 to 95% by weight of an extender.
5. The composition according to claim 1 , which is a flowable preparation comprising 0.1 to 80% by weight of the pyripyropene derivative of formula (I), 0.1 to 80% by weight of the other pest control agent selected from the group consisting of acetamiprid, imidacloprid and a compound of formula (II), 5 to 40% by weight of a dispersant, a thickening agent, an antifreezing agent, an antiseptic, and an antifoaming agent, and 20 to 94% by weight of water.
6. The composition according to claim 1 , which is a emulsifiable concentrate comprising 0.1 to 80% by weight of the pyripyropene derivative of formula (I), 0.1 to 80% by weight of the other pest control agent selected from the group consisting of acetamiprid, imidacloprid and a compound of formula (II), 1 to 30% by weight of an emulsifier and an emulsion stabilizer, and 20 to 97% by weight of an organic solvent.
7. The composition according to claim 1 , which is a micro granule fine comprising 0.1 to 80% by weight of the pyripyropene derivative of formula (I), 0.1 to 80% by weight of the other pest control agent selected from the group consisting of acetamiprid, imidacloprid and a compound of formula (II), 0.2 to 10% by weight of a solvent or a binder, and 70 to 99.6% by weight of an extender.
8. The composition according to claim 1 , which is a granule comprising 0.1 to 80% by weight of the pyripyropene derivative of formula (I), 0.1 to 80% by weight of the other pest control agent selected from the group consisting of acetamiprid, imidacloprid and a compound of formula (II), 0.5 to 30% by weight of a granulation assistant and a binder, and 20 to 98% by weight of an extender.
9. A method for protecting useful plants from pests, comprising applying an effective amount of at least one pyripyropene derivative of formula (I) or agriculturally and horticulturally acceptable salt thereof
wherein
Het 1 represents 3-pyridyl,
R 1 represents hydroxyl,
R 2 and R 3 each represent —OCO-c-C 3 H 5 , and R 4 represents hydroxyl, and at least one other pest control agent selected from the group consisting of acetamiprid, imidacloprid and a compound of formula (II),
wherein R 101 represents methoxycarbonyl, R 102 represents methyl, R 103 represents ethyl, X 101 , Y 101 , Y 102 , Y 104 and Y 105 represent a hydrogen atom, X 102 represents methyl, and Y 103 represents OCF 3 or OCF 2 CHF 2 , as active ingredients simultaneously or separately from each other to an area to be treated.
10. The method according to claim 9 , wherein the ingredients are simultaneously applied to the area to be treated.
11. A method for protecting useful plants from pests, comprising treating an object pest, an object useful plant, or a seed, a soil, or a cultivation carrier of the object useful plant with the pest control composition according to claim 1 .
