• Leaf stripe

  show symptoms of infection. Soil temperature during seedling emergence is critical for infection. Soil temperatures below 12 °C are most conducive for [...] for this disease and infection does not occur at soil temperatures above 15 °C. How to prevent Leaf stripe Produce seed in semi-arid environments without [...] use Use resistant cultivars Delay sowing in spring barley until soil temperature is higher than 12-15 o C Prevent plant diseases by optimizing plant potential

• Brown root rot, corky root rot

  prefers low temperatures. Therefore, optimal temperatures for disease development lie between 15 and 20 °C. Development reduces at temperatures above 20 °C [...] rotation with non-host crops Delay planting in the spring until soil temperatures are higher Mound soil around the stem to promote adventitious root growth

• Verticillium wilt

  optimum temperature for Verticillium albo-atrum is 21 °C and growth stops above 30 °C, whereas Verticillium dahliae has an optimum temperature around 25-27 [...] otia, small hard survival structures that can withstand high and low temperatures and dehydration. Verticillium dahliae also survives as hyphae (mycelium) [...] Verticillium wilt Start with clean soil or substrate by heating it at a temperature if at least 65 o C for a minimum of 30 minutes Use clean seed, tubers

• Chrysopa-E

  conditions Chrysoperla carnea is effective in a wide temperature range including low temperatures (average > 12°C/54°F). It is most effective at 20-28°C [...] receipt. If necessary, the product can be stored for 1-2 days. Storage temperature 8-10°C/47-50°F. Storage conditions In the dark. Recommended for you Predatory

• Black leg of seedlings

  too high or low temperatures or sudden fluctuations in temperature. Pythium ultimum mostly occurs at low soil or water temperatures and causes among others [...] nitrogen since this promotes the disease. In greenhouses: Prevent high temperatures immediately after planting. Avoid cold and excessive warm irrigation

• Damping-off

  water, too high or low temperatures or sudden fluctuations in temperature. Pythium aphanidermatum mostly occurs at higher temperatures in the soil or irrigation [...] nitrogen since this promotes the disease. In greenhouses: Prevent high temperatures immediately after planting. Avoid cold and excessive warm irrigation

• Early blight

  the crown. Sporulation of Alternaria occurs at temperatures from 2-4 °C up to 28-30 °C (optimum temperatures lie between 15 and 28 °C) and at a relative humidity [...] of over 90% or when the leaves are wet. Small differences in optimum temperature occur between species, but in general the risk of Alternaria infection

• Black rot of carrots

  storage. Sporulation of Alternaria occurs at temperatures from 2-4 °C up to 28-30 °C (optimum temperatures lie between 15 and 28 °C) and at a relative humidity [...] of over 90% or when the leaves are wet. Small differences in optimum temperatures occur between species, but in general, the risk of Alternaria infection

• Wheat bunt

  correlated to temperature and precipitation in the first 11 days after sowing, with maximum disease incidence at an average temperature of around 6 to [...] reduce the soil-borne inoculum Sowing winter crops early in the fall when temperatures are still above 15°C at the critical first 11 days reduces the risk of

• Root rot of carrot

  carrots. Temperature: Rhexocercosporidium carotae develops at temperatures ranging from -3°C to 25°C, with an optimum around 18°C; temperature affects both [...] infection can occur through the soil and the air. The fungus develops at temperatures ranging from -3°C to 25°C, with an optimum around 18°C. Lesions are dark
