Grower experiences worldwide


Farming in a place like Ireland presents its share of challenges, like keeping crops standing under high fertilizer regimens. Our family grows winter- and spring-sown wheat, barley, oats and rapeseed. We need products that provide reliable results each season — no matter the weather conditions. Traditionally, Irish growers have started with standard chlormequat chloride (CCC)-based products and followed with trinexapac and/or ethephon later in the season. Since early-season spring temperatures tend to be too low for standard chlormequat, the results can be disappointing.

Since it is formulated to work effectively at temperatures as low as 34°F, the main benefit we’ve seen from Eastman’s CCC-based product is reliable growth regulation and manipulation in early spring. We’ve seen how crops sprayed early will develop a better rooting system and produce a higher number of more evenly sized tillers. Crops will be noticeably stiffer and more even to walk across, which we believe will give a strong foundation for better grain yields.

We use Eastman’s Adjust™ SL plant growth regulator alone as a first-crop application. We follow up with a mix of Eastman’s product and trinexapac. We find no tank mix problems when paired with any other relevant agrochemical product.

Eastman’s plant growth regulator gives us peace of mind that we have chosen the best available technology for our wheat, barley and oat crops. It keeps crops standing and leads to the best possible grain harvests.

United Kingdom and continental Europe

The United Kingdom, France, Germany, Poland and many other EU countries enjoy the highest-yielding grain acreage around the globe. This positions them to be the most significant grain exporters of cereals. Nitrogen and growth regulators are the key tools applied together in these high-grain-yield countries.

For large grain-producing countries in the EU, CCC is a standard tool to protect yield and investments on wheat, barley, oats, rye and triticale. According to market studies, more than 50% of wheat acres receive a CCC treatment. Likewise, almost 50% of barley, oats, rye, triticale and spelt are also treated with CCC.

CCC is used in Europe as a very effective lodging control agent, which improves crop standing power. It is also integrated as a field management tool to establish fewer plants per square meter while applying higher nitrogen levels to maximize yield potential. Nitrogen and growth regulators are the key tools applied together in countries with high wheat yields.


In Canada, CCC has become the industry standard for maximizing yields and increasing efficiency of wheat, oats, rye, barley and triticale. Since its launch in 2014, CCC has gained widespread market acceptance in cereals because of its wide application window and safety for crops at low temperatures. CCC is an excellent tool for growers who want to maximize their yield potential by applying higher nitrogen rates where lodging is a concern. Growers in Canada recognize the value of CCC in their high-yielding and lodging-prone cereals’ application programs.

In Canada, product is sold under the brand name Manipulator™ through authorized Eastman distributor Belchim Crop Protection.
