Anthracnose can be a severe disease of intensely managed annual bluegrass and creeping bentgrass surfaces. The disease is most common on putting greens undergoing stressful growing conditions/management regimes and occurs predominately in mid-summer under hot/humid conditions or in the fall-spring months under cold wet conditions.
Blacklegged ticks (BLT) are a major public health concern as they can carry the bacteria that causes Lyme disease. Lyme disease is on the rise in Canada, as these ticks continue to spread into new areas. But with Envu solutions in conjunction with a comprehensive management program, you can help minimize the risks.
Brown patch can be a severe foliar disease of almost every cool-season turfgrass grown for putting greens, fairways, tees, and roughs. This disease is caused by the soil-borne fungal pathogen Rhizoctonia solani. Rhizoctonia diseases are perhaps the most widely recognized plant-pathogenic species across the globe and incites diseases on a wide host range including agricultural crops, trees, ornamental plants, and turfgrasses. The most susceptible grasses to infection include the bentgrasses, fescues, ryegrasses, and low-mown bluegrasses.
Chinch bugs are above ground pests that feed on turfgrass throughout the growing season. They can cause severe damage to most cool-season grasses. Chinch bug populations tend to be highest in years with prolonged hot, dry weather. But with proper scouting and effective application timing, you can neutralize this threat and keep your turfgrass healthy.
Dollar spot, caused by pathogens in the genus Clarireedia, is a widespread and very destructive turfgrass disease that occurs throughout the golf season in Canada. Dollar spot attacks most turfgrass species including annual bluegrass, bentgrasses, fescues, Kentucky bluegrass and perennial ryegrass.
Microdochium patch (Microdochium nivale) can be a tough problem on cool-season turf in late winter through early summer. This disease is also known as “Fusarium patch” in older references or as “pink snow mould,” though it can even develop when snow is absent.
Pythium turf diseases cause real problems for golf course superintendents. Pythium pathogens cause a host of different turfgrass diseases, affecting various parts of the plant, and each have unique environmental conditions favouring their development.
Pink and grey snow moulds are devastating turf diseases that occur on golf course putting greens, tees, fairways, and roughs in the presence of snow cover. These diseases are not only unsightly in the spring but can negatively impact turf health and make surfaces unplayable. Both pink and grey snow mould can affect all cool-season turfgrasses but tend to be more problematic on annual bluegrass and bentgrasses.
With spring recovery in full swing, existing and newly established turfgrass will need all the help it can get after a very slow start. Signature® XTRA Stressgard® should be considered as a tool in an effective spring recovery and establishment program.
The decline in turf quality and growth of creeping bentgrass and annual bluegrass is a major problem on putting greens during the summer months. Both biotic (diseases) and abiotic stresses (high temperature, high relative humidity, excessive soil moisture, poor air movement) may be contributing factors to the severity of summer decline.
Summer patch, caused by Magnaporthiopsis poae, is a root and crown disease that begins to show aboveground symptoms during periods of summer stress.
Take-all patch is an important root disease of all bentgrasses. It is caused by the fungus Gaeumannomyces graminis var avenae. The disease can appear in wet, cold conditions or in warm-hot conditions when plants are experiencing stress. Above-ground injury to bentgrass is due to root infection below ground because the fungus disrupts vascular tissue within the root cortex. Take-all survives on previously infected roots and it can be a recurring problem on infected plants.
Injury to turfgrass occurs from white grub larvae feeding on the roots, resulting in infested areas first turning yellow, then brown, and finally dying. When grub populations are heavy, areas of turf can be easily lifted from the soil.
Envu Stressgard® creates improved plant health that redefines normal. It is proven technology available in a portfolio of products that mitigates stress and delivers consistent turf quality.
Developing a fungicide and insecticide program is one of the most important action items for a golf course superintendent. This fueled our motivation at Envu to help develop a program with you in mind. Learn more about our Plant Protection Calendars and how they can help you keep your turf in great shape.
