Repairing the Genome’s Spelling Mistakes. Science 285: 316-318)に代表される塩基置換変異導入核酸を植物細胞内に導入して植物のアセチルCoAカルボキシラーゼ遺伝子やALS遺伝子等に部位特異的アミノ酸置換変異を導入することにより、アセチルCoAカルボキシラーゼ阻害剤やALS阻害剤等に耐性の植物を作出することができ、これらの植物に対しても本発明の農園芸用殺虫剤を使用することができる。
これら毒素の例及びこれら毒素を合成する事ができる組換え植物は、EP-A-0 374 753、WO 93/07278、WO 95/34656、EP-A-0 427 529、EP-A-451 878、WO 03/052073等に記載されている。
更に、本発明の農園芸用殺虫剤は、そのまま、又は水等で適宜希釈し、若しくは懸濁させた形で害虫防除に有効な量を当該害虫の発生が予測される場所に使用すればよく、例えば貯穀害虫、家屋害虫、衛生害虫、森林害虫等に散布する他に、家屋建材への塗布、くん煙、ベイト等として使用することもできる。
当該種子処理を行う「種子」とは、植物の繁殖に用いられる栽培初期の植物体を意味し、例えば、種子の他、球根、塊茎、種芋、株芽、むかご、鱗茎、あるいは挿し木栽培用の栄養繁殖用の植物体を挙げることができる。
本発明の使用方法を実施する場合の植物の「土壌」又は「栽培担体」とは、作物を栽培するための支持体、特に根を生えさせる支持体を示すものであり、材質は特に制限されないが、植物が生育しうる材質であれば良く、いわゆる土壌、育苗マット、水等であっても良く、具体的な素材としては例えば、砂、軽石、バーミキュライト、珪藻土、寒天、ゲル状物質、高分子物質、ロックウール、グラスウール、木材チップ、バーク等であっても良い。
土壌への施用方法としては、例えば、液体製剤を水に希釈又は希釈せずして植物体の株元または育苗用苗床等に施用する方法、粒剤を植物体の株元又は育苗のための苗床等に散布する方法、播種前または移植前に粉剤、水和剤、顆粒水和剤、粒剤等を散布し土壌全体と混和する方法、播種前または植物体を植える前に植え穴、作条等に粉剤、水和剤、顆粒水和剤、粒剤等を散布する方法等が挙げられる。
水田への施用方法としては、ジャンボ剤、パック剤、粒剤、顆粒水和剤等の固形製剤、フロアブル、乳剤等の液体状製剤を、通常は、湛水状態の水田に散布する。その他、田植え時には、適当な製剤をそのまま、あるいは、肥料に混和して土壌に散布、注入することもできる。また、水口や灌漑装置等の水田への水の流入元に乳剤、フロアブル等の薬液を利用することにより、水の供給に伴い省力的に施用することもできる。
移植を行う栽培植物の播種、育苗期の処理としては、種子への直接処理の他、育苗用苗床への、液状とした薬剤の潅注処理又は粒剤の散布処理が好ましい。また、定植時に粒剤を植え穴に処理をしたり、移植場所近辺の栽培担体に混和することも好ましい処理である。
本発明の農園芸用殺虫剤は、農薬製剤上の常法に従い使用上都合の良い形状に製剤して使用するのが一般的である。即ち、本発明の一般式(1)で表されるイミダゾピリダジン化合物又はその塩類はこれらを適当な不活性担体に、又は必要に応じて補助剤と一緒に適当な割合に配合して溶解、分離、懸濁、混合、含浸、吸着若しくは付着させて適宜の剤型、例えば懸濁剤、乳剤、液剤、水和剤、顆粒水和剤、粒剤、粉剤、錠剤、パック剤等に製剤して使用すれば良い。
更に必要に応じて機能性展着剤、ピペロニルブトキサイド等の代謝分解阻害剤等の活性増強剤、プロピレングリコール等の凍結防止剤、BHT等の酸化防止剤、紫外線吸収剤等その他の補助剤も使用することができる。
本発明の農園芸用殺虫剤は、防除対象病害虫、防除適期の拡大のため、或いは薬量の低減をはかる目的で他の農園芸用殺虫剤、殺ダニ剤、殺線虫剤、殺菌剤、生物農薬等と混合して使用することも可能であり、また、使用場面に応じて除草剤、植物成長調節剤、肥料等と混合して使用することも可能である。
