Rape needs growth stimulant

THINK about a growth stimulant instead of nitrogen if you want to boost oilseed rape this autumn.

That is the message from Newman Agrochemicals which points to the benefits seen in three years trials with its new rape and cereal management product Route.

Based on zinc ammonium acetate, it is described as an improved, more compatible formulation of Yeald, which the firms David Shelton estimates was used on 7-8% of the UK potato and sugar beet area this season.

Independent and replicated distributor trials suggest Route is more cost-effective and less leaching prone than nitrogen fertiliser in raising root and foliage weights and subsequent yields, says technical manager David Foster. On average the new product increased yields by 12% or 0.4t/ha (3.2cwt/acre).

"We see it as a valuable management tool especially where plant populations are below optimum and if pigeon damage is likely." Application timing will often coincide with post emergence herbicide spraying, says Mr Shelton. &#42
