Description

  The present invention relates to a pesticidal composition and a pesticidal method that exhibit an insecticidal effect enhanced by mixing fulvendiamide and a benzoylphenylurea insecticide, particularly teflubenzuron.

  Flubendiamide, which is an active ingredient used in the present invention, is a known compound and is known to be useful as a pest control agent (see, for example, Patent Document 1). In addition, it is known that expansion of target pests and the like can be expected by using a mixture of a phthalamide derivative and an insecticide (for example, see Patent Document 2).

JP 2001-131141 A JP 2003-12415 A

In agricultural work, it is necessary to spray various chemicals and the like many times during the growing period of crops, and the large number of spraying work places a heavy burden on farmers. For example, in fruit gardening and the like, cultivation is often performed on an inclined surface, and the burden is particularly heavy. Reducing the number of operations such as spraying is strongly demanded from the viewpoint of occupational health, which reduces the labor burden on farmers, and also from the economy, which reduces the production cost of agricultural products.
Flubendiamide is useful as a pest control agent, but depending on the type of insect pest and the application situation, the effect may not always be sufficient with an effective amount of spray applied in other situations. Therefore, there is a demand for a better pest control agent containing fulvendiamide.

  It is an object of the present invention to provide a novel pesticide composition that exhibits an excellent insecticidal effect continuously, a method for using the composition, and a method for controlling pests.

  As a result of studies to solve the above-mentioned problems, the present inventors have found that when benzoylphenylurea insecticides, particularly teflubenzuron, are mixed with fulvendiamide, compared with the case where each drug is used alone, The present invention has been completed by finding that an insecticidal effect more than expected can be obtained against fruit beetles and the like.

  That is, the present invention relates to a pesticidal composition containing fulvendiamide and a benzoylphenylurea insecticide, particularly teflubenzuron, a method for using the same, and a method for controlling pests.

  The pesticide for agricultural and horticultural use according to the present invention, fulvendiamide exhibits drug resistance when combined with a benzoylphenylurea insecticide, particularly teflubenzuron, and more effective than a single use of each drug. It is possible to effectively and continuously control a wider variety of pests, including pests, and pests that live in environments where effects are difficult to achieve. As a result, it can contribute to reducing the labor burden of farmers.

Used as an active ingredient of a pest controlling composition of the present invention, flubendiamide (ISO common name, chemical name: N ² - (1,1- dimethyl-2-methylsulfonyl-ethyl) -3-iodo -N ¹
-{2-methyl-4- [1,2,2,2, -tetrafluoro-1- (trifluoromethyl) ethyl] phenyl} phthalamide) (CAS registration number: 272451-65-7) is disclosed in It can be produced in accordance with No. 131141.

  The benzoylphenylurea insecticide may be any compound having an inhibitory action on chitin synthesis such as insects, such as triflumuron, bistrifluron, nobiflumurone, fullcyclothrone, teflubenzuron, flufenoxuron, diflubenzuron, hexaflumuuron. , Novallon and Lufenuron. Benzoylphenylurea insecticides can be used alone or in combination of two or more. Triflumuron, bistrifluron, nobiflumuron, fullcyclothrone or teflubenzuron are preferred, and teflubenzuron is particularly preferred. Benzoylphenylurea insecticides as these active ingredients, particularly teflubenzuron (ISO general name, chemical name: 1- (3,5-dichloro-2,4-difluorophenyl) -3- (2,6-difluoro) Benzoyl) urea) is also a known compound (see The Pesticide Manual, 12th edition (2000), etc.), and it can be produced according to the literature described in the literature or by purchasing a commercial product. It can be obtained.
