Biostimulants can play an important role in boosting crop growth and health – but it’s vital to use the right products at the right time. CPM reports. Although tempting to apply in a curative manner, biostimulants are most effective when used as plant health promoters, as part of a wider nutritional and plant protection programme. “There are some key considerations that contribute to the success of biostimulants – understanding the active ingredients, understanding what they do, and understanding when they work,” explains Don Pendergrast, head of technical services at UPL UK & Ireland. “The modes of action are different, so the outcomes can be different. Just like conventional chemistry, a planned programme will always yield the best results because products need to be used when they will have maximum impact.” Two of the most commonly used biostimulants on cereal crops are Ascophylum nodusum seaweed extracts – also known as oligosaccharides – and amino acids. Early application Oligosaccharides are recommended for use early in the programme. These concentrated complex sugars stimulate a plant to produce reductases that help with nutrient flow from the soil and translocation through the plant. This will improve the plant’s ability to access nutrition, as well as its overall…
