Description
本發明係關於一種穩定、水可懸浮的農藥組成物，其包含至少一種液態農藥成分以及至少一種固態農藥成分。The present invention relates to a stable, water-suspended pesticide composition comprising at least one liquid pesticide component and at least one solid pesticide component.
農藥係以組成物的藥品型式為基礎而分類，且特別是在用於水稻的農藥之實例中，既然其應用目的係為害蟲及例如水田中的禾草及雜草等不欲的植物之根除，針對能確實地施用需求量的農藥，同時也節省勞力之考慮，固態顆粒係為主要考量。然而，在粒狀組成物的例子中，問題是其不容易均勻地噴灑整個田地。此外，最近已試圖使用增加顆粒本身尺寸大小的技術來改善工作效率，其增加活性成分的量(除草活性成分)且降低噴灑量。Pesticides are classified on the basis of the drug type of the composition, and in particular in the case of pesticides for rice, since their application is for the eradication of pests and unwanted plants such as grasses and weeds in paddy fields. The solid particle system is the main consideration for the consideration of the ability to reliably apply the required amount of pesticides while also saving labor. However, in the example of the granular composition, the problem is that it is not easy to spray the entire field uniformly. In addition, attempts have recently been made to improve work efficiency by using techniques for increasing the size of the particles themselves, which increases the amount of active ingredient (herbicidal active ingredient) and reduces the amount of spray.
另一方面，除了固態顆粒之外，也有用於移植前處理的乳劑，以及用於移植後處理之水可懸浮的農藥組成物。液態農藥組成物，且特別是水可懸浮的農藥組成物，已因例如其降低環境負擔的能力、其處理簡易性，以及其均勻分散的簡易性等理由，於近年來引起了注意。然而，水可懸浮的農藥組成物具有例如在水分存在的情況下活性成分的不安定性、在混合二或更多種活性成分的例子中，且特別是在合併一液態成分與固態成分的例子中，均勻懸浮並分散所有活性成分的困難性，以及活性成分對分離、沈澱或聚集的敏感性之問題。On the other hand, in addition to the solid particles, there are also emulsions for pre-transplant treatment, and water-suspended pesticide compositions for post-transplant treatment. The liquid pesticide composition, and particularly the water-suspended pesticide composition, has attracted attention in recent years for reasons such as its ability to reduce environmental burden, ease of handling, and ease of uniform dispersion. However, the water-suspended pesticide composition has, for example, the instability of the active ingredient in the presence of moisture, in the case of mixing two or more active ingredients, and particularly in the case of combining a liquid component and a solid component. The difficulty of uniformly suspending and dispersing all active ingredients, and the sensitivity of the active ingredients to separation, precipitation or aggregation.
在調配混合二或更多種具有不同物理性質的活性成分之液態組成物的例子中，必須設計該組成物以便抑制所有活性成分的水解、沈澱及聚集，同時確保活性成分適當的分散、懸浮、乳化或其組合。雖然輔助劑例如乳化劑、乳化穩定劑及界面活性劑常被使用，仍有對應於活性成分與使用的輔助劑之間的相容性而引起活性成分的水解及聚集之實例。例如，在調配包含普拉草(pretilachlor)(一種在常溫下為液體且以氯乙醯醯胺【chloroacetoamide】為基礎的除草劑)，以及免速隆(bensulfuron－methyl)(一種在常溫下為固體且以磺醯脲為基礎的除草劑)之水溶液組成物的實例中，雖然為了懸浮及分散兩活性成分，其係必要使用例如乳化穩定劑或界面活性劑的輔助劑，端視使用的輔助劑類型而定，仍有例如免速隆顯著水解、沈澱及聚集發生的問題。In the case of formulating a liquid composition in which two or more active ingredients having different physical properties are mixed, it is necessary to design the composition in order to suppress hydrolysis, precipitation and aggregation of all active ingredients while ensuring proper dispersion, suspension, and active ingredient. Emulsified or a combination thereof. Although adjuvants such as emulsifiers, emulsion stabilizers, and surfactants are often used, there are examples of hydrolysis and aggregation of the active ingredients corresponding to the compatibility between the active ingredients and the adjuvants used. For example, in the formulation of pretilachlor (a herbicide that is liquid at room temperature and based on chloroacetoamide), and bensulfuron-methyl (a type at room temperature) In the case of an aqueous solution composition of a solid and sulfonylurea-based herbicide, in order to suspend and disperse the two active ingredients, it is necessary to use an adjuvant such as an emulsion stabilizer or a surfactant, and the auxiliary of the use Depending on the type of agent, there are still problems such as rapid hydrolysis, precipitation and aggregation.
例如，日本特開平10－287503號公報描述了由作為農藥活性成分之以磺醯脲為基礎的除草劑，及/或作為具有雜草除草活性的除草劑有效成分、具有平均聚合度2000或更少及皂化度69到90 mol%的聚乙烯醇所組成的水溶液懸浮組成物，而水具有令人滿意的組成安定性、改善的分散性，且可藉防止稻體上化學品的附著而預防化學損害。此外，日本特開平9－183704號公報描述木質素磺酸鹽的添加提供一種包含具有優越長期儲存安定性之以磺醯脲為基礎的除草劑之水性懸浮組成物的取得。For example, Japanese Laid-Open Patent Publication No. Hei 10-287503 describes a sulfonylurea-based herbicide as an active ingredient of a pesticide, and/or as a herbicide active ingredient having weed herbicidal activity, having an average degree of polymerization of 2,000 or more. An aqueous suspension composition composed of polyvinyl alcohol having a saponification degree of 69 to 90 mol%, and water having satisfactory composition stability, improved dispersibility, and prevention by preventing adhesion of chemicals on the rice body Chemical damage. Further, Japanese Laid-Open Patent Publication No. Hei 9-183704 describes the addition of a lignosulfonate to provide an aqueous suspension composition comprising a sulfonylurea-based herbicide having excellent long-term storage stability.
