CROP YIELD-INCREASING AGENT

摘要

PURPOSE:To provide an agent exhibiting an remarkable yield-increasing activity for grain crops such as rice and beans by containing N6-[2-(N-methoxy-N- methylamino)ethyl] adenine or a salt thereof as an active ingredient. CONSTITUTION:The subject agent contains a compound of the formula or its salt with hydrochloric acid, phosphoric acid, acetic acid, etc., as an active ingredient. The compound of the formula is employed in a form of emulsion, water- dispersible powder, powder, solution, etc., together with a liquid diluent such as an alcohol, water or DMF, a solid carrier such as talc, diatomaceous earth or phenolic resin, a surfactant (e.g. alkylbenzene sulfonic acid sodium salt), a dispersing agent, an adhesive agent, etc. The compound of the formula is applied in a rate of 0.01-1g per 10a of the field to a legaminous crop (e.g. soybean, azuki, bean, kidney bean, or peanut) between its flowering time and the grain filling early time of its grain and to the leaf and stem of a gramineous crop (e.g. rice, wheat or corn) between its booting time and its grain filling early time.
