農作物保護（雑草防除）分野におけるモンサント社との長期的協力関係について住友化学、および同社の米国での農薬開発･販売子会社であるベーラント USA 社は、このほど、米国の大手種子・バイオ・化学メーカーであるモンサント社との間で、農作物保護（雑草防除）分野における長期的な協力関係の構築について合意し、契約を締結いたしました。
本件は、モンサント社の本社があるミズーリ州セントルイスにおいて、現地時間の10 月 19 日(火)9 時（日本時間:19 日 23 時）に、3 社の連名による添付文書の内容を発表しております。
モンサント社は世界的な除草剤ブランドである ’Roundup®’ と、同剤への耐性を付与したさまざまな遺伝子組み換え作物である ‘Roundup Ready’ の種子を組み合わせた効果的、経済的かつ簡便な雑草防除体系である ‘Roundup Ready system’ を農業分野に対して従来から推奨しておりましたが、2011 年以降は米国内において、住友化学・ベーラント USA の除草剤ラインナップを雑草防除体系に組み込み’Roundup ReadyPlus’として推奨することとなります。具体的には、大豆、綿、テンサイを栽培する農家がこの雑草防除体系で推奨される種子と除草剤（住友化学の製品を含む）の使用を選択した場合、農家に対してモンサント社から様々な製品サポートが提供されます。
今回の協力関係構築によって、住友化学のフルミオキサジン(Flumioxazin)を有効成分に含む除草剤である Valor®SX、Valor XLT、Gangster®、Fierce™、およびクレトジム(Clethodim)を有効成分とする Select®といった一連の製品群は、モンサント社の雑草防除体系に長期的に組み込まれ、’Roundup®’ の有効成分であるグリホサート(Glyphosate)に対する抵抗性を持った雑草の防除を含む様々な雑草問題への農家の要請に応えることができるようになります。
住友化学では、これまでグリホサートに対する抵抗性を有する雑草への対策に有効な除草剤の開発と販売を進め、子会社のベーラント USA を通じて米国で高い使用実績を獲得しておりますが、今回の提携により当社の農薬ビジネスが米国内において更なる発展をとげることを大いに期待しております。
また、住友化学とモンサント社は、さらに、ブラジル、アルゼンチンなど南米各国での協力関係構築に向けても協議を進めることに合意しています。
