Description

  The present invention relates to a method for controlling rice rice mildew and a composition for controlling rice rice mildew.

Rice (Oryza sativa, Oryzaglaberrima) and shows the Gramineae rice plants in the genus is classified into two japonica is ecotype (O. Sativa subsp. Japonica) and Indica species (O. Sativa subsp. Indica) . Starch, the main ingredient in the edible portion of rice, is classified into amylose and amylopectin due to the difference in molecular structure, and varieties containing about 20% amylose (粳) have a amylose content of 0% due to genetic defects. Varieties that are categorized as Mochi (ち). Specific varieties include Koshihikari, Nihonbare, Akitakomachi, Kirara 397, Kinuhikari, Hitomebore, Nanatsuboshi, Hoshino Yume, Haenuki, Domannaka, Sasanishiki, and Hinohikari. Koganemochi, Miyakoganemochi, Asahi Kaoru, Fujikura Kaoru, Hiyokumochi, Himenomochi, Mochihikari, Yume no Hachimochi, Hakuchomochi, Toyohata Mochi and Wataboshi, etc. Ikuhikari, Milky Pearl, Himenomochi, etc. are suitable for sake brewing, such as Yamada Nishiki, Hyakumangoku, Miyama Nishiki, Omachi, Hachiman, Hachimannishiki, Ginfu, Yumesansa, Wakamizu, Yume no incense and ferry Hoshi Yutaka, Hoshi Aoba, Kusanohoshi, Kusa Yutaka, Nishi Aoba, Tachi Aoba, Minami Yutaka, etc. It is. In addition, upland rice, black rice, red rice, green rice, and special varieties bred using disease resistance and insect resistance as an index are also included in rice.

  The heading in rice means that the head appears. Specifically, it is a phenomenon that emerges from the leaf sheath of the stationary leaf as it is pushed out when the young panicle that has differentiated at the tip of the stem develops by being wrapped in the leaf sheath of the uppermost leaf (static leaf) and matures as a spike. In particular, the earliest time at which ears are confirmed is the beginning of heading, the time at which about 50% of the stems are headed is referred to as the heading time, and the time at which about 90% is headed is referred to as the heading time. In rice, heading is generally observed about 50 days after rice planting and about 80 days after late rice, but the timing of heading also depends on the variety and the weather. In general, any variety requires about 30 days from the formation of a leaf to the formation of a young panicle.

Rice rice mildew is a rice disease caused by Villosiclava virens and occurs frequently in cool areas. It occurs especially under conditions such as low temperature and high humidity, and more than half of the ears are affected, leading to a decrease in yield. Rice rice mildew disease only affects rice spikelets (rice buds), forming yellow-green masses at first, then forming a large amount of thickened and thickened thick-wall spores that become powdery and approaching the harvest season Forms black sclerotia. Damage is said to have a considerable impact not only on the current loss of diseased but also on an increase in unexpected grains and a decrease in the weight of a thousand grains. Moreover, since the number of dead rice increases and the thick-wall spores formed on the rice cake adhere to the milled rice, quality deterioration is also a problem.

  Although the mechanism of rice rice mildew infection has not been clearly elucidated, it has been estimated that the fungus infects the ear by airborne infection because the infection site by the fungus is the ear of the rice (Non-Patent Document 1, 2, 3). Therefore, it is presumed that the time when the ear, which is the infected part, appears (around heading) is the appropriate control period, and the control effect by spraying the drug around the heading has been studied (Non-patent Document 4).

  The optimal period for controlling rice rice mildew is greatly different when using spraying agents such as wettable powder, granular wettable powder, flowable powder and powder, and when treating granules. In the case of a spraying agent, the effect is reduced except for 10 days before heading, so the appropriate control period is about 10 days before heading, and this period is selected and controlled. In particular, a high control effect can be expected by spraying a copper powder about 10 days before heading. However, when using a spraying agent, it may not be able to be sprayed about 10 days before heading, which is an appropriate period of control due to rain.

  Moreover, in the case of granules, the degree of compound adsorption varies depending on the type of soil, so the appropriate control period by the granule treatment is about 3 to 4 weeks before heading (Non-patent Document 5). However, about 3 to 4 weeks before heading, which is the appropriate control period for cimeconazole granules, paddy field management was in the mid-drying season, and there was a disadvantage that it was necessary to put it in a flooded state in order to treat it at this time. Furthermore, when treating cimeconazole granules to flooded paddy field soil, several weeks were required from the time when the compound was absorbed into the rice body before shifting to the part that required control.

  In addition, the time around 10 days before heading is generally the time when the panicle length of rice is about 3 to 15 cm. In addition, 3 to 4 weeks before heading is generally a period from the time when rice leaves are formed until the juvenile head reaches a state of about 1 to 2 mm.

However, the effect by the control by the conventional application time is not enough, and the chemical | medical agent which shows the stable high effect on the spot, and its processing method were desired.

  It is an object of the present invention to provide an improved method for controlling rice koji, which has been insufficient with conventional treatment methods using disease compositions.

  As a result of repeated studies on the optimal period of control for rice rice mildew, the present inventor has hitherto been considered to be the most effective time, before the ear that is the site of infection (if spraying agent, about 10 days before heading) By treating a specific plant disease control composition at a time completely different from the heading 3 to 4 weeks before heading, that is, when there is no ear that is an infection site of Aspergillus oryzae.
