• Powdery mildew

  contact with water for no more than a few hours. Powdery mildew spores, either ascospores or conidia, don’t need nutrients or water for germination. In general [...] perithecia, structures containing ascospores. Ascospores have not been found yet for all powdery mildew fungi and especially in greenhouse crops they don’t play [...] Silicon and/or Calcium nutrition hardens the cell walls and makes it harder for the fungi to enter the leaves To reduce chances of powdery mildew in greenhouses

• Pomegranate wilt complex

  discoloured bands in the stem and roots. Disease cycle The fungus survives for more than 7 years in infected plant debris and soil. The pathogen spreads [...] of solution per tree to the root zone by making the ring around the tree for three times at weekly intervals. Mix 10gm Vici Routz SP in 10 liter of water

• Leaf stripe

  temperature during seedling emergence is critical for infection. Soil temperatures below 12 °C are most conducive for this disease and infection does not occur [...] The leaf splits at the end which makes it look shredded. This is typical for this disease. Infected plants may be stunted and heads may be distorted and

• Gummy stem blight

  the main source of dispersal of disease upwards in the crop and the conidia for spread of the disease downwards. How to prevent Gummy stem blight Before cropping: [...] pots and plant parts from previous crop that may serve as inoculum source for the new crop prevent condensation on all plant parts at all times Extra Silicon [...] Silicon and/or Calcium nutrition hardens the cell walls and makes it harder for the fungi to enter the leaves Pick flowers within two days after opening in

• Blight of pepper

  temperatures between 15 and 23 °C and higher water content than is optimal for crop growth. Phytophthora overwinters in roots, infected tubers and bulbs [...] either by germinating sporangia or by zoospores produced in the sporangia. For germination on above-ground plant parts, leaf wetness is required. Dispersal [...] the water content of the soil or substrate is higher than normal or optimal for crop growth. How to prevent Blight of pepper Apply hygiene measures, like

• Fusarium head blight or scab

  general, most Fusarium specieshave a similar life cycle. Fusarium overwinters for many years in the soil and on crop residues of infected plants as chlamydospores [...] takes place as infection of the roots at the root tip or in small wounds, for example where lateral roots branch off from the tap root. Gibberella zeae [...] Disinfect tools, machinery and irrigation water in greenhouses Prevent stress for the plants Ensure there is adequate soil drainage Apply nitrogen in the form

• Apple collar rot

  temperatures between 15 and 23 °C and higher water content than is optimal for crop growth. Phytophthora overwinters in roots, infected tubers and bulbs [...] either by germinating sporangia or by zoospores produced in the sporangia. For germination on above-ground plant parts, leaf wetness is required. Dispersal [...] the water content of the soil or substrate is higher than normal or optimal for crop growth. How to prevent Apple collar rot Apply hygiene measures, like

• Grape downy mildew

  should focus on reducing infection pressure, limiting favorable conditions for disease development, and maintaining protective coverage on susceptible tissues [...] dense canopy growth These measures help create less favorable conditions for disease development but are usually not sufficient on their own under high [...] (IPM) programs. The free-living amoeba Willaertia magna C2c Maky is known for its ability to produce a wide range of bio-active compounds involved in microbial

• Apple scab

  s this increases to 12-28 hours of leaf wetness for successful infection. Conidia also need water for germination. How to prevent Apple scab Use resistant [...] population as well as macro-organisms like earth worms are not harmed by for example application of compounds against stem canker, since they help in

• Phytophthora blight

  temperatures between 15 and 23 °C and higher water content than is optimal for crop growth. Phytophthora overwinters in roots, infected tubers and bulbs [...] either by germinating sporangia or by zoospores produced in the sporangia.
