Jasmonates and insect control Jasmonates are a class of plant hormones that play a crucial role in plant responses to stress, including defense against insect herbivores. They are involved in signaling pathways that regulate plant defenses, particularly against chewing insects and other herbivores. Jasmonates help plants mount a defense response to minimize damage and deter […]

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 […]

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 […]

Lodging occurs when the crop falls over and does not return to a standing position. Crop lodging can be very costly to producers and can pose many challenges during harvest. For instance, it is common to see secondary growth on the flattened crop extending maturity and diminishing grain quality. For the past couple of years, harvest in some parts […]

Plant growth regulators (PGRs) and plant growth stimulators (PGSs) are naturally-occurring or synthetic compounds that, when applied to plants, modify their physiological processes, and growth and development habits. In plant cells, they stimulate specific enzymes or pathways and help regulate metabolism. The term “PGR” is widely used in Western Canada to refer to products that […]
