Abstract
Description
本発明は、農薬粒剤に関する。 The present invention relates to pesticide granules.
水稲の栽培においては、育苗箱に農薬製剤を施用することにより、該育苗箱で生育した幼苗を水田に移植するに際し、前記農薬製剤に含有される農薬活性化合物も水田に施用され、該農薬活性化合物の効力が持続している間は、水田へのあらたな農薬活性化合物の施用を必要としない。それ故、このような施用形態に好適な多くの農薬製剤が開発されている（例えば、特許文献１参照）。 In the cultivation of paddy rice, by applying a pesticide preparation to the seedling raising box, when the seedlings grown in the seedling raising box are transplanted to the paddy field, the pesticide active compound contained in the pesticide preparation is also applied to the paddy field, and the pesticide activity is applied. As long as the efficacy of the compound lasts, no new application of the pesticide active compound to the paddy field is required. Therefore, many pesticide preparations suitable for such application forms have been developed (see, for example, Patent Document 1).
一方、殺虫活性化合物としてオキサゾスルフィルが知られている（例えば、特許文献２及び特許文献３参照）。 On the other hand, oxazosulfyl is known as an insecticidal active compound (see, for example, Patent Document 2 and Patent Document 3).
本発明は、含有されるオキサゾスルフィルの溶出が制御され、且つ物理化学的性状の経時変化が抑制された、オキサゾスルフィル含有農薬粒剤を提供することを課題とする。 An object of the present invention is to provide an oxazosulfyl-containing pesticide granule in which the elution of the contained oxazosulfyl is controlled and the change in physicochemical properties with time is suppressed.
本発明者等は、このような農薬粒剤を見出すべく検討の結果、オキサゾスルフィル、アルファ澱粉、ノニオン性界面活性剤、炭酸カルシウム及びクレーをそれぞれ特定量含有する農薬粒剤とすることにより、該粒剤に含有されるオキサゾスルフィルの溶出が制御され、また、該粒剤の物理化学的性状の経時変化が抑制されることを見出した。
すなわち本発明は、以下の〔１〕〜〔５〕の通りである。
〔１〕 オキサゾスルフィル０．５〜５重量％、
アルファ澱粉４〜７重量％、
ノニオン性界面活性剤０．１〜５重量％、
炭酸カルシウム３〜１０重量％、及び
クレー５０〜９２重量％
を含有する農薬粒剤。
〔２〕 前記ノニオン性界面活性剤がポリオキシエチレンアルキルエーテル及びポリオキシエチレンアルキルアリールエーテルからなる群より選ばれる少なくとも１種のノニオン性界面活性剤である〔１〕に記載の農薬粒剤。
〔３〕 前記ノニオン性界面活性剤がポリオキシエチレントリスチリルフェニルエーテルである〔１〕に記載の農薬粒剤。
〔４〕 前記クレーがロウ石である〔１〕〜〔３〕のいずれかに記載の農薬粒剤。
〔５〕 農薬粒剤１０ｇとイオン交換水９０ｇとを混合したときの２０℃におけるｐＨが９．４以上である〔１〕〜〔４〕のいずれかに記載の農薬粒剤。
As a result of studies to find such pesticide granules, the present inventors have made pesticide granules containing oxazosulfyl, alpha starch, nonionic surfactant, calcium carbonate and clay in specific amounts. It has been found that the elution of oxazosulfyl contained in the granules is controlled, and the change over time in the physicochemical properties of the granules is suppressed.
That is, the present invention is as follows [1] to [5].
[1] Oxadiazolefil 0.5 to 5% by weight,
Alpha starch 4-7% by weight,
Nonionic surfactant 0.1 to 5% by weight,
Calcium carbonate 3-10% by weight, and clay 50-92% by weight
Pesticide granules containing.
[2] The pesticide granule according to [1], wherein the nonionic surfactant is at least one nonionic surfactant selected from the group consisting of polyoxyethylene alkyl ether and polyoxyethylene alkyl aryl ether.
[3] The pesticide granule according to [1], wherein the nonionic surfactant is polyoxyethylene tristyrylphenyl ether.
[4] The pesticide granule according to any one of [1] to [3], wherein the clay is pyrophyllite.
[5] The pesticide granule according to any one of [1] to [4], wherein the pH at 20 ° C. when 10 g of the pesticide granule and 90 g of ion-exchanged water are mixed is 9.4 or more.
本発明の農薬粒剤は、オキサゾスルフィル、アルファ澱粉、ノニオン性界面活性剤、炭酸カルシウム及びクレーをそれぞれ特定量用いることにより、含有されるオキサゾスルフィルの溶出を抑制することができ、また、物理化学的性状の経時変化、特に硬度が経時的に低下することを抑制することができる。 The pesticide granules of the present invention can suppress the elution of oxazosulfyl contained in the pesticide granules by using specific amounts of oxazosulfyl, alpha starch, nonionic surfactant, calcium carbonate and clay, respectively. In addition, it is possible to suppress changes in physicochemical properties over time, particularly a decrease in hardness over time.
本発明の農薬粒剤（以下、本粒剤と記す）はオキサゾスルフィル（ｏｘａｚｏｓｕｌｆｙｌ）を含有する。なお、オキサゾスルフィルは下記式（１）
本粒剤はアルファ澱粉を含有する。本粒剤におけるアルファ澱粉の含有量は、４〜７重量％の範囲である。 This granule contains alpha starch. The content of alpha starch in the granules is in the range of 4-7% by weight.
