Jasmonic and salicylic acids (JA and SA) are plant phytohormones that play key roles in resistance/tolerance to biotic and abiotic stresses and interact with the other families of phytohormones to modulate growth and development. Understanding these PGRs and their roles has given modern agriculture new tools to fight diseases and pests, reduce the build-up of resistance to fungicidal and insecticidal active ingredients and enhance crop tolerance to a wide range of abiotic stresses, such as wet, dry, cold and hot.
Brassinosteroids (BRs) are growth hormones from the steroid family that are found in all plant species. They have a high-growth promoting activity, particularly in pollen and anthers, and take their name from the pollen of canola (Brassica napus), where they were initially discovered. BRs are involved in the control of cell division, elongation and differentiation throughout the growing season and are crucial for plant growth and development. And, acting as growth regulators, they are essential to many responses to stress.
Manganese (Mn) is an essential micronutrient that while needed in small amounts, plays a key role in photosynthesis. Mn sparks the photosynthesis process by splitting water after Photosytem II (PSII) fixes light to initiate the conversion of CO2 and water into carbohydrates.
Manganese deficiency is widespread in Canadian Prairies and Eastern Canada, reducing growth and development of many crops and restricting yields and quality. In this post we will specifically examine the role of manganese in plants, the consequences if its deficiency and provide solutions to mitigate the crop stress due to manganese shortage or deficiency.
In the pursuit of better and bigger crops, farming is becoming more technologically advanced and capital intensive. The need to find ways to save money, while continuing to reach for those high yield goals, is more important than ever for Canadian producers. If this sounds like a conundrum that you’re facing, soil testing might be the answer.
The United Nations General Assembly has declared 2020 the International Year of Plant Health (IYPH). This global declaration, which follows International Year of Soil in 2015, is meant to raise awareness on how protecting plant health can help end hunger, reduce poverty, protect the environment and boost the economy of many countries around the world.
