Kick-off autumn fieldwork with timely positive harvest management to prevent problems in this season’s crop carrying over until next season. Being in control of harvest timing ensures there is enough time to complete all fieldwork ahead of drilling autumn crops.

Make Time for Stubble Management

Efficient harvesting will be more important than ever to give sufficient time for the best pre-planting weed control and resolving any soil problems after the wettest winter in living memory for many. An effective pre-harvest spray programme of Round Up (glyphosate) is an essential part of preparing for next autumn. More consistent crop dryness and lack of green weed growth ensures the most effective straw and chaff chopping and spreading.

Get Treatment Timing Right

Don’t be tempted to spray too early, it doesn’t bring combining forward and can affect yield and grain quality.  In oilseed rape, only apply glyphosate after moisture levels drop below 50%, typically when two thirds of seeds in the part of the canopy carrying most of the yield change from green to brown. Apart from anything else, this will minimise immature ‘red’ seeds in the sample.

The same 30% moisture level applies to pre-harvest spraying in cereals. This is reached when all the grains from the centre of the ear hold an indentation from a firm thumbnail press.

Treat Difficult Crops Carefully

After such a difficult season, achieving the maximum possible yield is a top 

priority. Heavily-waxed and uneven OSR, backward wheats, and thin, weedy spring crops will benefit most from careful treatment

Wait until crops are ready to combine

Although, here is a statutory minimum interval from glyphosate spraying to combining of 14 days for OSR and seven days for cereals, the time taken for crops to dry down very much depends on the weather.

This means they should only be combined when they’re fit – which may be up to three weeks after spraying in some cases for oilseed rape.

Choose the best formulation

The biggest challenge with glyphosate is getting it into the plant. Modern Roundup formulations stand out here for their ability to deal with heavily waxed cuticles, reliability under challenging conditions, and outstanding rainfastness. Medium-coarse sprays, together with water volumes, pressures and settings giving thorough canopy coverage and penetration are equally important, with applications early in the day useful in hot weather.”
