Why is blackgrass a problem?
Black-grass can greatly affect yield and cause contamination issues at harvest. A few weeds one year can become a significant weed burden over a short time frame. Destroying (spraying with glyphosate or cutting) patches of black-grass in winter wheat in the first week of June will reduce viable seed return.Preventing seed return is the most important part of reducing blackgrass populations. If the post-emergence control is not satisfactory, make a decision pre-Christmas and plan a spring crop. Where infestations are worst, consider the use of glyphosate or whole crop but timing will be critical.Blackgrass is one of the most problematic and damaging agricultural weeds for winter wheat in Western Europe. Severe infestations can result in yield loses of up to 70%, squeezing farm productivity and ultimately imperilling our food security.Preventing seed return is the most important part of reducing blackgrass populations.

What is the common name for black-grass?
Alopecurus myosuroides is an annual grass, native to Eurasia, found in moist meadows, deciduous forests, and on cultivated and waste land. It is also known as slender meadow foxtail, black-grass, twitch grass, and black twitch. Alopecurus myosuroides. Black-grass is one of the biggest challenges to profitable arable farming in the main wheat growing areas of the UK. On some farms growers have had to adopt dramatic shifts to their rotations, cultivations and even fundamental land use changes to get on top of the weed.Distributed all over the British Isles, black-grass (Alopecurus myosuroides) is most abundant in cultivated land in South-East England. However, it has gradually spread North and West, recently arriving in South-East Scotland and Northumberland. It remains rare in northern Scotland.Black-grass is a native annual grass weed that occurs throughout the UK but is found mainly in the cereal growing areas of southern and eastern England. It rarely occurs outside of cultivated land and is most abundant in winter crops. Black-grass is often found spreading into arable fields from the field margins.The black grass is decaying surface leaves that are likely caused by the combination of a disease called brown patch, intense heat and dry soil conditions – all prerequisites for this fungal disease to manifest itself. Rain (or irrigation) and cooler temperatures are important to enhance recovery in these areas.Black-grass likes and thrives in conditions of poorly structured, anaerobic soils, with low levels of organic matter, low aeration, consolidation, compaction. No farmer has a black-grass problem.
Where does black-grass grow best?
Grow ophiopogon in moist, but well-drained soil. It prefers the slightly acidic, fertile, humus-rich soil typical of shady woodland areas. Choose a spot in full sun or partial shade. The black foliage varieties will darken more in a sunny location. For black mondo grass, the quintessential time to transplant is during the crescendo of spring into the cusp of summer, offering balanced climates for root establishment. Choose shaded locales with well-draining soil. Gentle handling is paramount to protect delicate roots.You can grow black mondo grass in full sun to partial shade in the North, but grow it in full sun to achieve the darkest foliage color. But, in the South, the plant profits from a location in partial shade to cope with the hotter summer weather.To fertilize your Black Mondo Grass (Ophiopogon planiscapus ‘Nigrescens’), apply a balanced, slow-release fertilizer—such as a 10-10-10 formula—in early spring as new growth begins to emerge. This light feeding supports vibrant foliage color, healthy root development, and steady growth throughout the season.
What does black-grass do?
Blackgrass is one of the most problematic and damaging agricultural weeds for winter wheat in Western Europe. Severe infestations can result in yield loses of up to 70%, squeezing farm productivity and ultimately imperilling our food security. Black-grass thrives on heavy land, particularly where drainage is poor. On light land it is a problem on wetter areas. About 80% of seeds germinates in the autumn. Hot, dry summers see strong early autumn-germination; cool wet autumns see increased dormancy and delayed germination.Grass growth reaches its maximum at a temperature of 50°F, which mainly occur during the spring months from March to May.Planting in late spring and early summer gives warm-season grasses the advantage of warm soil and early seasonal rains, which help keep soil moisture available during germination and establishment. Moderate spring weather helps spring-planted grass seed flourish.
What kills black-grass?
Chemical control should start with the use of glyphosate on stubbles, stale seedbeds or cultivated soils to ‘burn-off’ any emerged black-grass prior to drilling the crop. Use crop rotation to manage black grass Given the right conditions, crops can provide their own weed control by competing with weeds for light and space. Higher seed rates, variety choice and drilling date can all push things in the crop’s favour, meaning herbicides can finish the job.
Why do I have black-grass?
The black grass is decaying surface leaves that are likely caused by the combination of a disease called brown patch, intense heat and dry soil conditions – all prerequisites for this fungal disease to manifest itself. Rain (or irrigation) and cooler temperatures are important to enhance recovery in these areas. I’ve Blackened the Grass with Moss Killer! It will also blacken the grass for the following reasons: Lawn sand is the easiest way to blacken the grass if not distributed evenly. If applied as a liquid, the concentration you made up is too intense; therefore, check your calculations and information.Black Lawn” The reason for this is due to a fungal disease that infects lawns that are stressed.Common Causes Black Spot can infect all grasses, both warm and cool season varieties. During warmer weather, massive deluges combined with heat and humidity create the ideal conditions for Black Spot.Step 4: Adjust Watering Practices – Overwatering contributes to the development of black fungus. Water your lawn deeply but infrequently, preferably in the morning, to allow the grass to dry during the day. Step 5: Apply Fungicide – For severe infestations, applying a fungicide may be necessary.
