Description

  The present invention exhibits an insecticidal effect enhanced by mixing a phthalamide derivative represented by the general formula (I) with a plant surface spray agent, in particular, a fungicide, a fruit surface protectant, a foliar fertilizer, etc. containing calcium. The present invention relates to a pesticidal composition, a method for using the same, and a method for controlling pests.

The phthalamide derivative represented by the general formula (I), which is an active ingredient used in the present invention, is a known compound (see, for example, Patent Document 1 and Patent Document 2). The phthalamide derivative is useful as a pest control agent. It is known. In addition, it is known that the use of a mixture of the phthalamide derivative, which is the active ingredient of the present invention, and an insecticide, can be expected to expand the target pest, reduce the dose, and achieve a synergistic effect (for example, Patent Documents). 3). In the general description, the possibility of mixing lime sulfur mixture, basic copper sulfate and the like as a combination composition having a synergistic effect with a phthalamide derivative is described.
However, no example has been disclosed in which a synergistic effect is produced by a combination of a phthalamide derivative and a fungicide. In addition, “calcium” contained in an inorganic copper agent such as basic copper sulfate, zinc sulfate lime solution, sterilizing agent such as lime sulfur mixture, etc., exemplified as being able to be mixed with the phthalamide derivative of the present invention There is no special mention. In addition, there is no description of a pest control composition combining a phthalamide derivative and a fruit surface protective agent typified by lime liquor, or an activity improving effect exhibited when these are mixed or applied at the same time. There is no suggestion.

  Phthalamide derivatives are useful as various pest control agents, but for certain pests, especially fruit beetles, etc. It may not be. There is a need for an effective method for further enhancing the effects of pesticides containing phthalamide derivatives so that they can be stably used at lower application concentrations for a wider range of pests and application scenes. .

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.
Bordeaux liquor, zinc sulfate lime liquor and lime sulfur mixture are spraying agents conventionally used as bactericides, and lime liquor is commonly used as a face-protecting agent. Since these physical properties are strongly alkaline, when using insecticides, there is often a problem in that the effect is reduced due to decomposition of the insecticides, so the insecticide and these calcium-containing components are treated simultaneously. I couldn't.

  The present invention summarizes (1) the improvement of insecticidal activity of pesticides containing phthalamide derivatives, and (2) treatment of fungicides and fruit surface protective agents containing calcium, and insecticide spraying treatment. It is an object of the present invention to provide a pest control composition that can satisfy both of the above and a method of using the pest control composition, and a more efficient method for controlling pests using the pest control agent.

  As a result of researches to solve the above-mentioned problems, the present inventors have found that when a phthalamide derivative is mixed with a fungicide containing a lime component and / or a face protecting agent containing calcium, etc., it is effective. It was found that there was no decline. Rather, surprisingly, by using the mixture, it was found that an insecticidal effect more than expected was obtained as compared with the case where the phthalamide derivative was used alone. The present invention was completed by finding that the insecticidal effect was enhanced by simultaneously treating a phthalamide derivative and a plant surface spraying agent, particularly a plant surface spraying component containing calcium.
