TRIAL RESULTS FOR 2025/26 SELECTION PACTS® Maize Hybrids

Dear UK & Ireland Pioneer Maize Grower, We are very pleased to present the latest maize PACTS® trial results following an extensive programme of trials across the maize growing areas of the UK and Ireland in 2024. This book also provides details of the Pioneer maize hybrid range and Pioneer Brand Silage Inoculant range for 2025. PACTS is an abbreviation for ‘Pioneer Accurate Crop Testing System’. We conduct these multi-location onfarm trials to generate local data that enables us to describe the potential performance of the Pioneer maize hybrids we offer for sale. If you choose to sow a Pioneer...

Pioneer brand inoculants Our comprehensive proprietary range of silage inoculants have been developed to reduce dry matter losses and improve silage quality. Whether you are making grass silage in cool challenging environments or maize silage in ideal conditions, applying the most appropriate Pioneer silage inoculant can make a potentially significant difference to your profitability. You can see the full range of our silage inoculants inside this brochure. 2024 was another challenging year with unpredictable and sometimes extreme periods of weather. The 2024 PACTS host farmers, and their contractors,...

Pioneer Accurate Crop Testing System PIONEER INOCULANT PRODUCT GUIDE 8 INDIVIDUAL SITE RESULTS 44 The purpose of PACTS® trials Whether a particular maize hybrid realises its full genetic potential depends largely upon how well it is adapted to the local environment, how successfully the crop is managed, and of course what weather occurs during the season. The PACTS Trial Results are provided to help growers identify which Pioneer hybrids may be best suited to their own location and circumstances. PACTS trial protocols, including sowing and harvest date determination, reflect actual practice on...

The selection of a particular hybrid for cultivation inevitably varies according to the different criteria a grower has. In many situations yield is of paramount importance but earliness of maturity and silage quality are examples of other critical hybrid features. No single hybrid will suit all situations. Growing a successful maize crop depends at least upon selecting a hybrid with the most appropriate genetic potential, growing it on an appropriate site and managing it a manner that will meet the chosen objectives. The following factors are just a few of the key ones that can have a very significant...

The development of M3 genetics and the effect on production efficiency. Developing maize hybrids with a dent grain texture that are early flowering and fully adapted to the cool growing conditions found in the UK & Ireland is a key activity for Corteva plant breeders. Such hybrids bring the potential for high starch content silages, but also silages that are higher in rumen degradable starch. This long-term breeding effort began to pay off with the introduction of P7034. This is the first Pioneer maize hybrid to meet the company’s M3 advancement criteria. It has provided UK growers with the ability...

PIONEER BRAND SILAGE INOCULANT GUIDE Pioneer brand silage inoculant technology The use of Pioneer silage inoculants can lead to lower dry matter losses, higher nutritional value, and improved aerobic stability. Complementary, proprietary, and highly efficient strains of lactic acid producing bacteria are incorporated into many Pioneer silage inoculants to convert sugar rapidly and efficiently to lactic acid. The activity of these bacterial strains leads to a much faster drop in silage pH with many beneficial consequences including higher dry matter recovery, increased microbial protein and a...

NITROGEN STABILISERS Improve crop performance and sustainability through better nitrogen management. How Instinct works Instinct works by stabilising ammonium (NH4+). It inhibits the Nitrosomonas bacteria, slowing down the conversion of ammonium to nitrite. This keeps more ammonium in the soil, for longer. Reducing losses of nitrogen to the environment is one approach to improve nitrogen use efficiency. Ammonium is not vulnerable to leaching from soil with rainfall, nor will it be converted to nitrous oxide in waterlogged soils. Instinct®, containing Optinyte™ technology, reduces environmental...

A unique way that enables maize to capture nitrogen all season. What is BlueN? BlueN™ is a nutrient efficiency biostimulant for use in a broad range of crops including maize. It contains Methylobacterium symbioticum, a bacteria found in nature, which fixes nitrogen from the air and converts it to ammonium for the plant. How does BlueN work? BlueN delivers a constant flow of nitrogen to the plant. BlueN converts atmospheric N2 into ammonium which can be used by the plant. BlueN enters the plant through the stomata from where it can colonise the leaves. N2 Plants generate methanol during normal...
