The presence of orange/pink spores may also be visible [...] result in shrivelled grains with a chalky white or pink appearance, although this is not always the case. Life cycle and appearance of Foot rot of cereals [...] results in dark-brown staining of the lower nodes. Long dark streaks may also appear at the stem base. On older plants, infection can produce a true foot

Pierce's disease of grapevine

Part of a green leaf suddenly dies and [...] depends on the plant species: in peach, bacteria are found in high numbers in the roots, whereas in plum, high numbers are found in leaves and fruits. The bacteria [...] die. This happens faster in younger vines than in older ones and faster in susceptible cultivars (within 2-3 years) than in more tolerant cultivars, which

Bacterial canker of tomato

usually white with a brown centre. In potato, the disease usually only occurs in the second half of the season. The first symptoms are wilting of the lower leaves [...] the plants in greenhouse crops and by water in field crops, for example through splashes of rain or irrigation. Both in greenhouses and in the field, spraying [...] structures Use a crop rotation in field crops of at least two years and alternate with a non-host crop Apply deep-ploughing to stimulate the decay of crop residues

Downy mildew of Cucurbits

This is actually the sporulation of the pathogens extruding [...] or surviving mycelium sporangia are formed, structures in which zoospores are produced. However, in downy mildews, sporangia often germinate directly and [...] leaves and after a while new spore-bearing structures are protruding from the stomata. Because there are more stomata on the underside of the leaf, this

Caterpillar control in greenhouse crops

Pheromone traps are available for monitoring adults of several species. Installing a range of different traps in problem areas at the beginning of the season [...] leaves, or flowers, that have been spun together, in holes in stems, flowers, or fruit, or in the bark of trees. Important species include light brown apple [...] that occur in the greenhouse belong to the Noctuidae, which is the largest of all the lepidopteran families. Their forewings are mostly shades of brown and

Vidi Fol (Fortafol)

This results in higher photosynthesis [...] required amount of water Add the correct amount of Vidi Fol to the water Mix thoroughly Fill the tank with the remaining amount of water The pH of the solution [...] systems: Dissolve the required amount of Vidi Fol in the appropriate amount of water for the device that is used The pH of the solution should be between 5

Mode of action Flies are attracted by the luring substance and enter the trap. Once inside, they cannot escape and drown in the luring substance [...] Drososan trap with 200 ml of the luring substance Refill when the luring substance has evaporated or is saturated with flies Dosage For the number of traps
