Whitefly

triangular shape and hold their wings in a vertical position over their body when at rest. Color: As their name suggests, whiteflies are usually white or pale [...] different species of whitefly can be most easily distinguished from each other at the pupal stage. The adult emerges from the hardened cuticle of the pupa through [...] environment less favorable for whiteflies.

Early blight

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 (RH) of [...] brown lesions on stem and foot. On fruits, dark sunken, leathery lesions occur at the side of the stem. Life cycle and appearance of Early blight From the primary [...] Prevent damage during harvest (in potato and carrot). Post-harvest storage at 0-1 o C. A. brassicae and A. brassicicola : adjust the sowing date to avoid

Black rot of carrots

occasionally appear on the carrots at harvest but usually occur only during post-harvest storage. Sporulation of Alternaria occurs at temperatures from 2-4 °C up [...] up to 28-30 °C (optimum temperatures lie between 15 and 28 °C) and at a relative humidity (RH) of over 90% or when the leaves are wet. Small differences [...] Prevent damage during harvest (in potato and carrot). Post-harvest storage at 0-1 o C. A. brassicae and A. brassicicola : adjust the sowing date to avoid

Cottony soft rot

Sclerotia germinate at temperatures between 4 and 26 °C with an optimum between 13 and 15 °C. Germination and infection mostly take place at high soil water [...] soft root ( Sclerotinia sclerotiorum ) infection are water-soaked lesions at the stem base. The plant above it wilts and rots. White, fluffy fungal mycelium

At a 24 hours average temperature below 17°C/63°F the [...] if possible approximately 75 cm under the plant head Avoid hanging cards at places exposed to direct sunlight Dosage The dosage of En-Strip depends on [...] 1-10 per m 2 /release. Releases should be repeated until control is achieved. At increasing temperatures it may be better to switch to the use of Enermix or

Damage [...] lose their turgor or the leaf tips turn yellow, for example in flower bulbs. At first, the plants recover during the night, but later the plants wilt irreversibly [...] recirculating nutrient solutions Increase the distance to the main substrate at the start by using higher substrate blocks for the seedlings In field crops:
