Method for preventing transplanting rice diseases

The present invention relates to a method for preventing diseases of transplanted rice and/or controlling pests of animals.

Insecticide treatment of rice seeds directly planted in rice fields is known. However, there is still no technology for pesticide application (Section III; common technique of pesticide application, seed disinfection) for the purpose of preventing diseases and/or controlling animal pests in transplanted rice. Publication: 1998, pp. 133 -139, edited by Pesticide Science Society of Japan, published by Japan Plant Protection Association).

Further, a disinfection method for a seed-infected disease is also described, in which the seed is treated with a seed disinfectant after being immersed in water or after germination, but the prevention of diseases or insect pests in the rice field is not described (Japanese Patent Application Laid-Open No. 9224424, Japanese Patent Application Publication No. 11028006, Japanese Patent Application Publication No. 11049612).

For the preventive treatment of diseases of transplanted rice and/or the control of animal pests, pesticides are sprayed on rice fields or nursery boxes. However, spraying pesticides on rice fields to prevent rice diseases and/or controlling animal pests after transplanting rice into rice fields has the problem that a large amount of pesticides or pesticides are not durable. Moreover, spraying pesticides in the nursery box can reduce the amount of pesticides compared to rice fields, but in some cases the amount of pesticide used is still large and the effect is not long enough.

Accordingly, it is an object of the present invention to improve these disadvantages and to provide a method for preventing disease and/or controlling animal pests by transplanting rice as compared to the amount used for conventional seedling box treatment to significantly reduce the amount of pesticides. It is simple and cheap, and has long-term residual effects in rice fields.

Through special studies to solve the above problems, the inventors of the present invention have found that by treating rice seeds with isotianil before seeding in a nursery box, the amount of pesticides may be significantly reduced compared to the conventional nursery box treatment. Make pesticides last longer. In the definition of the present invention, long-lasting utility means that disease prevention and/or control of animal pests is still observed 53 days or more after transplanting. Preferably, disease prevention and/or control of animal pests is still observed 67 days or more after transplanting. Optimally, disease prevention and/or control of animal pests is still observed 80 days or more after transplanting.

On the other hand, it has been found that in some cases, when the seeds are treated with other pesticides such as probenazol, tiadinil and the like, harmful effects are caused, and when the seeds are treated with reduced pesticides In order to reduce harmful effects, sufficient pesticide effects cannot be obtained after transplanting to rice fields. The present invention has been completed based on the above findings.

There is no particular limitation on the method of attaching the composition containing the idini to the rice seed. As for the powder coating method, for example, there is a method in which rice seeds and pesticides are placed in a rotating drum and the rice seeds are uniformly coated with the pesticide by rotating the drum. As for the method of spraying the pesticide, for example, there is (1) a method in which a pesticide is directly sprayed on a rice seed dropped by a funnel or the like by using a suitable nozzle, and (2) a flow in which a vibration is conducted. a method of attaching a funnel to a nursery box, and spraying the pesticide directly onto the rice seed using a suitable nozzle when the rice seed bounces through the board, and (3) a drum in which a rice seed is passed through the funnel Between the top of the pre-box and the pesticide, the pesticide is sprayed on the rice through the drum. In the method of spraying a small amount of rice seeds on a rice seed, a method in which the rice seeds are placed in a rotary machine such as a mortar mixer and a predetermined dose of the pesticide is uniformly sprayed on the rice seeds with a suitable nozzle can be used. In addition, it is also possible to use the rice seed in a plastic bag or a suitable container which is two to three times the volume of the rice seed, and after adding the composition containing the idini, it is tightly closed (in the case of a plastic bag) It is a method in which the bag is filled with air and the bag mouth is closed, so that the whole bag is inflated, shaken and agitated, so that the pesticide is dispersed into the entire container or in the bag. In the case of spraying a large amount of rice seeds, a nozzle may be installed in the transportation means connected to the seeding machine of the seedling box to spray the pesticide, and if necessary, the rice seed and the pesticide may be mixed.

According to another method of treating rice seeds, the pre-germinated rice seeds are treated in a seed processor specially developed to treat pre-germinated rice species rather than dry rice seeds. The seed processor includes a drum having an inner diameter and a spiral cone having a slurry shaft and a helical ramp around the pulp shaft for mixing the seed with at least one pesticide. This spiral cone is incorporated into the drum and has a tolerance between the ramp and the drum of the spiral cone. In order to treat the pre-germinated seeds without treatment of the buds during the treatment (here: mixing process), it is necessary to determine the ratio of the inner diameter to the allowable amount. Preferably, the ratio of the allowable amount to the inner diameter of the cylinder is set to 1:10.

The seed processor further includes a bucket for containing at least one pesticide and an air compressor for pressurizing at least one pesticide sprayed onto the cylinder. At least one pesticide can be sprayed onto the cylinder via at least one nozzle (PCT/EP2012/058927, unpublished).

Preferably, the composition comprising sinidin is used in the range of 0.1 to 7 g ai/kg, in particular from 2 to 4 g ai, in terms of dry seed weight (weight of rice before soaking) /kg. Preferably, the weight of the rice seed after soaking or the weight of the rice seed after germination is in the range of 0.125 to 10 g a.i./kg, especially from 2.5 to 5 g a.i./kg. Preferably, the unit area of the rice seedlings after transplanting into the rice field is in the range of 30 to 180 g ai/ha, preferably in the range of 40 to 140 g ai/ha, more preferably 60 to 120 g ai. The range of /ha is more preferably in the range of 40 to 80 g ai/ha, most preferably in the range of 50 to 70 g ai/ha.

This amount is much lower than the amount of pesticide commonly applied to rice seeds.

In the case of rice seeds, it is preferred after soaking and before or after germination. of. The soaking method for the rice seed is also not limited, and preferably, for example, the cumulative temperature of ‧ days at 60 to 140 ° C (for example, 7 to 10 days at 13 to 14 ° C) allows the rice seed to absorb sufficient moisture. After the soaking treatment, after smearing, spraying or the like with the composition containing the idini, the rice seeds only need to be sown, germinated and cultivated in the nursery box. In the case of treating the rice seed after germination, for example, after soaking, the yttrium-containing composition is attached by smearing or spraying or the like at 20 to 40 ° C, preferably at 25 to 35 ° C for 10 to 30 hours. Preferably, the rice is expanded after 20 to 24 hours. After the treatment, the rice seeds are sown in a nursery box (for example, the size is 60 cm x 30 cm x 3 cm).

The method of cultivating the rice seedlings in the seedling box, cultivating the rice seedlings, covering the soil, transplanting the seedlings to the rice fields, and cultivating the rice after transplanting is not particularly limited, and a generally known method can be employed. For example, after the seeds are covered with soil, the seedling boxes are placed on the incubator and the seeds are allowed to germinate, and then the seedling boxes are moved to the nursery room and further cultivated. It is only necessary to transplant the cultivated seedlings into the rice fields using a tiller and the like. There is no restriction on the method of cultivating the rice after transplanting it into the rice field, and the rice can be cultivated according to a conventional method.

Although there is no particular limitation on the intended disease using the method of the present invention, the pesticide can be used against, for example, Plasmodiophoromycetes, Oomycetes, Zygomycetes, Ascomycetes. , Basidiomycetes, Deuteromycete s, and Bacteria. In particular, the disease derived from plant pathogens is selected from the group consisting of red deer disease ( Gibberella fujikuroi ), rice fever [ Pyricularia oryzae ], rice husk disease [ Cochliobolus miyabeanus ], rice sheath blight [triggered by Rhizoctonia solani ], rice bacterial Shell blight [triggered by Burkholderia glumae ], rice leaf blight [caused by Xanthomonas oryzae pv. oryzae ], rice bacterial blight [pod shell] Burkholderia glumae and bacterial ovals ( Acidovorax avenae ). In particular, it can effectively prevent diseases derived from filamentous fungi and/or microorganisms, such as rice. Fever, rice husk , scab, rice sheath blight, rice bacterial blight and bacterial blight.

In the definition of the invention, all rice pests can be controlled by the method of the invention. According to a preferred embodiment of the present invention, the controllable rice pest is selected from the group consisting of Lissorhoptrus oryzophilus , Oulema oryzae Kuwayama , Delphacidae , and Black-tailed spider mites ( N ephotettix cincticeps ), Hydrellia griseola (rice leaf miner), Parnara guttata (rice worm), Naranga aenescens Moore , Cnaphalocrocis medinalis ), Chilo suppressalis and Stenchaetothrips biformis (rice horse ).

The invention is illustrated on the basis of the following examples.

Example 1

The rice seed is treated as a seed by a method in which the germinated rice seed (expanded) The swelling is obtained by soaking the dried seeds, and containing 3 g of the active ingredient (denidini) per 1 kg of dry rice (the aqueous suspension composition is from the nitidine: about 20 parts by weight) , surfactant (tristyrylphenol): about 1 part by weight, acrylic resin: about 3 parts by weight, using propylene glycol as a diluent: 10 parts by weight, other additives (antifoaming agent, preservative, thickener and The analogs: a total of 5 parts by weight or less and the portion thereof is water) are placed in a plastic bag and thoroughly mixed. Next, 150 g of rice seeds (in terms of dry rice weight) were sown into each seedling box (60 cm x 30 cm x 3 cm) and immediately covered with soil. After the seeds were covered with soil, the nursery boxes were placed on a nursery rack and placed at 30 ° C for 3 days. After budding, the nursery box is moved to the nursery room and greened and cultivated according to conventional methods. The cultivated seedlings were mechanically transplanted (about 2.5 leaf stage), 20 boxes per 10a (that is, 20 boxes per 0.1 ha). Fertilization management and the like according to local practices.

Example 2

A rice sample was prepared according to the same conditions as in the examples, but using the same formulation having 6 g of active ingredient per 1 kg of dry rice.

Comparative example 1

A rice sample was prepared under the same conditions as in Example 1, but without the use of a nitidine formulation.

Comparative example 2

A rice sample was prepared by applying a formulation (containing 2% of the arsenic particle composition) on the growth chamber instead of seed treatment. That is, 2.2 L of the culture soil was placed in a nursery box and 1 L of water was irrigated onto the culture soil, and then 150 g of seeds (in terms of dry rice weight) were sown, and then uniformly distributed in each box. 50 g of this formulation was sprayed and the incubator was immediately covered with soil. After the seeds were covered with soil, the incubator was placed on a culture rack and placed thereon at 30 ° C for 3 days. After budding, the nursery box is moved to the nursery room and greened and cultivated according to conventional methods. The cultivated seedlings were mechanically transplanted (about 2.5 leaf stage), 20 boxes per 10a (that is, 20 boxes per 0.1 ha). Fertilization management and the like according to local practices.

Test of disease symptoms
