  According to the present invention, in a pest control technique in a facility cultivation house, a farmer can accept a stable and stable and safe agricultural product by minimizing the use of a chemically synthesized insecticidal active compound. It becomes possible to develop a general-purpose technique such as a proposal method of a pest control system that is extremely useful for production.

  The present invention relates to a method for proposing a pest control system in a facility cultivation house capable of reducing the application rate of a chemically synthesized insecticidal active compound, and a pest in a facility cultivation house proposed by the method. The amount of a chemically synthesized insecticidal active compound used in a pest control method in a facility cultivation house and a pest control method in a facility cultivation house characterized by pest control based on a control system. And a method for suppressing the development of drug resistance in pests against chemically synthesized insecticidal active compounds used in pest control methods in house for greenhouse cultivation. And the said invention is a technique which comprises a part of the comprehensive control technique called IPM.

First, a method for proposing a pest control system in a facility cultivation house capable of reducing the application rate of chemically synthesized insecticidal active compounds will be described.
The pest control system proposed in the method includes pests to be controlled (preferable basic pests include, for example, aphids, and Alaska spiders and / or cigarettes, spider mites, and other species (Thrips and / or Or whiteflies and / or slips), etc.), and the three basic elements of the pest control method based on the total cultivation period of the crop and the combination of the chemical control method and the biological control method. It is a pest control system composed of Such a configuration is easy to understand as a specific image as shown in FIGS. 1 to 4, for example, and is easy to grasp conceptually. It is extremely useful for making proposals.
The first step is a step of identifying an insecticidal active compound that is used for pest control in a pest control system in a facility cultivation house.
Here, the “facility cultivation house” is a house that can stably cultivate crops by protecting the plant body from rain and ensuring a stable temperature. For example, (1) a medium-sized tunnel for covering cultivation , Large unheated tunnel or large heated tunnel, (2) vinyl-covered horticultural vinyl house, (3) activate pollination activities of flowering insects, or perform night illumination (long-day treatment) The glass greenhouse etc. which can promote flowering by or can adjust cultivation environment automatically by automatic control functions, such as a computer, can be mentioned.
In addition, the “pest control system” means, for example, a combination of various pest control methods, biological, chemical and physical pest control methods to reduce the pest population below the level that causes economic damage, and It is one of the pest population management systems for sustaining low levels, not only reducing the damage caused by pests, but also providing value-added agricultural products, drug resistance problems against chemically synthesized insecticidal active compounds It means a unified combination that brings farmers, consumers, etc., mitigation and conservation of the agricultural environment.

Next, the second step is a step of selecting an insecticidal active compound having a substantial effect on natural enemies against pests to be controlled among the identified insecticidal active compounds.
Here, as the “natural enemy against the pests to be controlled”, for example, the following can be specifically mentioned.

  In addition, “substantial efficacy” refers to the ability of the above-mentioned natural enemies to eliminate the pest control effect of the natural enemy in a statistically significant amount in an effective amount at which the insecticidal active compound exhibits control effect on the pest. I mean.

Next, in the third step, among the chemical control methods using the selected insecticidal active compound, at least one chemical control method is a natural enemy against the pests to be controlled, and all year round. This is a process for exchanging with a biological control method that uses either a natural enemy that does not sleep or a natural enemy that is active in winter.
In the step, when there are a plurality of selected insecticidal active compounds at the same time on the control calendar, all the chemical control methods using the selected insecticidal active compound are usually applied to the pests to be controlled. What is necessary is just to replace | exchange for the biological control method which uses either the natural enemy which is a natural enemy and does not sleep all year round, or the natural enemy active in winter. On the other hand, when there are a plurality of selected insecticidal active compounds in a non-contemporaneous period on the control calendar, all or part of the chemical control method using the selected insecticidal active compound is usually the subject of control. What is necessary is just to replace | exchange for the biological control method which uses either the natural enemy which is a natural enemy with respect to a pest and does not sleep all year round, or the natural enemy active in winter.

  Next, the fourth step is a step of proposing a pest control system including the replaced biological control method.

In the method of the present invention, the biological control method may be a biological control method having an environmental condition in which the growth rate of natural enemies used in the biological control method exceeds the growth rate of the pests.
As such an environmental condition, for example, selecting a cultivation type of a crop that adapts to a temperature condition included in a suitable temperature range for development of natural enemies, the temperature condition (specifically, for example, a temperature condition of a growth zero point or higher, preferably Is higher than the flight limit temperature, more preferably, the temperature condition above the egg-laying limit temperature), the natural increase rate of the natural enemy population exceeds the natural insect pest population by setting the temperature in the facility cultivation house, etc. What should I do? It should be noted that information related to the growth zero of the natural enemy and the pest, the flight limit temperature, the egg-laying limit temperature, etc. is collected and accumulated in advance, and the development of the natural enemy rather than the growth of the pest based on the accumulated information. It is also possible to provide a biological control method that can provide environmental conditions having temperature conditions that are more appropriate.
In order to confirm whether the biological control method has an environmental condition in which the growth rate of natural enemies exceeds the growth rate of the pest, it may be based on an empirical rule, and it is not only a quantitative means but also a qualitative method. Such as checking the environmental conditions as described above, and the number of natural enemies found per crop (for example, one or more in 10-20 flowers), etc. You may investigate and observe the existence, or observe and confirm the increase of indigenous natural enemies that naturally occurred after the release of natural enemies.
In the biological control method, when releasing natural enemies, it is also preferable to release natural enemies by releasing them several times, such as about 2 to 3 times, at intervals of one week from the initial stage of occurrence of the pests.

In the method of the present invention, the natural enemy used in the biological control method is at least one natural enemy selected from the anteater, the hornet, the parasitic bee, the honeybee, and the Bacillus thuringens (BT). And the release amount of the natural enemy is 0.01 to 100 heads / m ² (when excluding natural enemy microorganisms) or 1 to 5 kg / ha (in the case of natural enemy microorganisms), and the biological control method The sum of the doses of all insecticidal active compounds used in the chemical control method being replaced is the sum of the doses of all insecticidal active compounds used in the pest control system prior to being exchanged for the biological control method. 50% or more is preferable. Examples of other natural enemies include dust mites.

Examples of natural enemies used in the biological control method include, for example, common bees such as the common anteater against Thrips and Srips, And at least one natural enemy selected from among the natural enemies against whiteflies and the natural enemies Bacillus thuringens (BT). Examples of other natural enemies include dust mites that are natural enemies against spider mites.
As described above, these natural enemies may be those already on the market, or those that exist in nature and have been collected, or those that are made in-house.
The amount of released natural enemies as described above is 0.01 to 100 / m ² (excluding natural enemy microorganisms) or 1 to 5 kg / ha (in the case of natural enemy microorganisms), preferably 0.5 to 30 / m ² It may be 1 to 5 kg / ha (in case of natural enemy microorganisms).
All the insecticidal active compounds used in the chemical control method exchanged for the biological control method have various combinations resulting from the third step, and the total application amount of the insecticidal active compound in the combination. Is calculated, the exchange ratio with respect to the total of the application rates of all the insecticidal active compounds used in the pest control system before being replaced with the biological control method can be calculated.

  In the method of the present invention, the step of replacing the chemical control method with the biological control method further includes a step of predicting / assessing a risk related to the influence of natural enemies used in the biological control method on the indigenous biota. It is preferable. This step is beneficial for further enhancing the future safety of the biological control method. For example, by investigating the physiological host range by host specificity test of natural enemies, or by investigating the ecological host range, the risk related to the impact on indigenous biota can be predicted and evaluated. Good. Based on the results of the prediction / evaluation, measures such as avoiding the use of natural enemies with a wide host range may be implemented as necessary.

In the method of the present invention, in order to reinforce the pest control effect, the proposed pest control system is effective against the pests to be controlled, and is substantially a natural enemy to the pests to be controlled. The pest control system may be a chemical control method using an insecticidal active compound having no efficacy, which is added at or just before the biological control method is performed.
In general, biological control methods may be inferior to chemical control methods in terms of immediate effects or sharp efficacy depending on the combination of complex conditions. In order to reinforce the chemical, a chemical control method using an insecticidal active compound may be used in a spot manner. However, in the chemical control method used in this case, in order not to lose the effect of the biological control method, the chemical control method has an effect on the pests to be controlled and is substantially a natural enemy to the pests to be controlled. It is necessary to use an insecticidal active compound which does not have a potent efficacy.

Here, "the insecticidal active compound having an effect on the pests to be controlled and having no substantial effect on natural enemies to the pests to be controlled"
(A) Neonicotinoid insecticidal active compounds such as clothianidin (trade name: Dantotsu, sales company: Sumika Takeda Agricultural Chemicals) (the pests to be controlled are various pests such as thrips, aphids, whiteflies and leafhoppers) Insecticidal compounds suitable for certain cases)
(B) Pyriproxyfen (trade name: Ranault, sales company: Sumitomo Chemical Co., Ltd.) (insecticidal active compound suitable when the pests to be controlled are thrips, whiteflies, and slips)
(C) Pyridalil (trade name: Pleo, sales company: Sumitomo Chemical Co., Ltd.) (pesticide active compound suitable when the pests to be controlled are Spodoptera litura, Tobacco moth, Thrips, and Clamidae)
(D) Spinosad (trade name: Spinoace, sales company: Nippon Soda) (insecticide active compound suitable when the pests to be controlled are thrips and thrips)
(E) Clofenapyr (trade name: potato, sales company: Japanese pesticide) (pesticide active compound suitable when pests to be controlled are spider mites and thrips)
(F) Pymetrozine (trade name: chess, sales company: Syngenta) (pesticide active compound suitable when the pests to be controlled are aphids, leafworms, whiteflies)
(G) Rufenuron (trade name: match, sales company: Syngenta) (pesticide active compound suitable when the pest to be controlled is whitefly)
It is preferable that it is at least 1 or more insecticidal active compound chosen from these.

Similarly, in the method of the present invention, predicting or evaluating the generation amount of the pests to be controlled and the control effect of the pests to be controlled by the biological control method, and
When it is evaluated that the control effect is insufficient with respect to the generated amount, it has an effect on the pest as the control target and has a substantial effect on the natural enemy against the pest as the control target. The chemical control method using an insecticidal active compound may further include a step of re-proposing a pest control system added at or just before the time of using the biological control method.
Here, “the process of predicting or evaluating the generation amount of the pest as the control target and the control effect of the pest as the control target by the biological control method” uses a past empirical rule. Also good. The “insecticidal compound having no substantial effect on natural enemies against the pests to be controlled” is, for example, at least one insecticidal compound selected from the above (a) to (g). Preferably there is.

In the present invention, the proposed pest control system is preferably a pest control system to which a physical control method is added.
The physical control method differs in the appropriate implementation time depending on the type of the physical control method.For example, the physical control method may be implemented in the entire period from the beginning to the end of the pest control system, or limited to the necessary period. May be implemented.

In the present invention, examples of the physical control method include a pest blocking method and / or a pest attracting method.
Here, the “pest blocking method” is a method of eliminating damage by a pest by cutting off a pest entry route, for example, a method of closing a pest entry port with a net or the like. The “pest attracting method” is a method of attracting a pest with a color, an insect pheromone, etc., and killing it with an adhesive.
In particular, it is extremely effective to block the entry of pests from the outside by attaching nets to open parts such as windows that the facility cultivation house has, and further to suppress the outflow of natural enemies from the inside, preferably mentioned Can do.

  Examples of the above-mentioned “insect blocking method” include insect control nets having a scale of 3 to 6 mm when the insect pest to be controlled is a large insect such as Spodoptera litura, Tobacco moth, When the pest to be controlled is a micropest such as aphids, whiteflies, slips, or leafhoppers, an insect net having a size of 0.2 to 4 mm can be used.

In addition, as the above “pest attracting method”, for example, when the pest to be controlled is an aphid, the yellow pest attracting colored adhesive sheet / tape, and the pest to be controlled is whitefly, tobacco whitefly, and other whitefly Yellow pest-attractive colored adhesive sheet / tape, blue pest-attractive colored adhesive sheet / tape if the pest to be controlled is a thrips such as Chano yellow thrips, Citrus thrips, Southern thrips, etc. In the case where the pest to be controlled is a leaf fly such as bean leaf fly, a yellow pest attracting colored adhesive sheet / tape can be used.
Note that the yellow pest attracting colored adhesive sheet / tape attracts bees and parasitic enemies of natural enemies, so the bees and natural enemies parasitoids were released at the facility cultivation house where the adhesive sheet / tape was installed. Is preferably avoided.

What is necessary is just to use the above adhesive sheets and tapes as follows, for example.
Adhesive sheets and tapes will be installed on both sides of the facility cultivation house and at the place of the house support. Cut the adhesive sheet / tape into a length of 1.5-2m, fix it on a column with a height of 0.5-1m, and place it at a distance of 2-3m.

  Next, a pest control method in a facility cultivation house characterized in that pest control is carried out based on the pest control system in the facility cultivation house proposed by the method of the present invention will be described. It is a pest control system consisting of three basic elements: the target pest, the entire cultivation period of the crop, and the pest control method based on a combination of chemical control method and biological control method. Corresponds to the first to third steps in the method of the present invention described above, and the detailed description thereof is basically the same as the description in the method of the present invention described above.

  Next, a method for reducing the amount of chemically synthesized insecticidal active compound used in the pest control method in the facility cultivation house will be described. The pests to be controlled by the pest control system and the crops It is a pest control system composed of three basic elements of a whole cultivation period and a pest control method based on a combination of a chemical control method and a biological control method. The detailed description is basically the same as the description in the above-described method of the present invention.

  Next, a method for suppressing the development of drug resistance in a pest against a chemically synthesized insecticidal active compound used in a pest control method in a facility cultivation house will be described. The pest control system is a control target. It is a pest control system composed of three basic elements: pests, the entire cultivation period of crops, and pest control methods based on a combination of chemical control methods and biological control methods. This is equivalent to the first to third steps in the method of the present invention, and the detailed description is basically the same as the description in the method of the present invention described above.

In the present invention, secondarily, it is important to draw out the power of naturally occurring natural enemies, and in many cases, naturally occurring natural enemies increase after the natural enemies are released. Furthermore, it is extremely effective in the following situation.
In other words, it is difficult to add work that requires more labor than at present, and the use of natural enemies after detailed and complicated monitoring is not easy at the present time (it is necessary to have more merit than the labor spent on monitoring). Therefore, if you summarize the conditions of natural enemy use that farmers can accept,
(1) No monitoring is required.
(2) Inject natural enemies according to the pest control calendar,
(3) Although there is a method of continuously introducing natural enemies from the beginning of cultivation, we expect natural enemies from the point of increase in expenses due to the release of natural enemies in the absence of pests and the effects of natural enemies are unclear. Shorten the pest control period,
It becomes.

  Hereinafter, the method of the present invention will be described in more detail with reference to examples, but the method of the present invention is not limited thereto.
