Downy mildew of cucumber is one of the most important diseases of cucumber plants. It can wreck hectares of cucumber farms within a very short time. This disease causes huge losses every year.
Downy mildew of cucumber is caused by an oomycete called Pseudoperonospora Cubensis. Though downy mildew is often explained to be caused by fungi, this is not true. This disease is caused by oomycetes which are very similar to fungi. The ooomycetes belong to the water mold group.
The pathogen causing downy mildew is disseminated by wind and water. Once the spore lands on the leaves of a cucumber plants, they sporulate and germinate.
This disease spreads very fast in humid and rainy conditions. The spores can travel up to 1,000km within a few days.

Solutions that do not work for Downy Mildew of Cucumber
I am sure that you have heard a lot of pesticides sellers in Nigeria telling you to buy fungicides with mancozeb and copper oxide as their active ingredients.
Most fungicides sold in Nigeria are highly substandard; this is common with copper and mancozeb fungicides. The reckless usage of copper and mancozeb has also increased the resistance of the pathogens to these fungicides.
The truth is that these fungicides do not prevent or cure the strains of downy mildew in Nigeria. You will just continue to waste your money by applying these fungicides.
Some good agronomic practices like not touching the foliage of your plants when wet, planting tolerant varieties, avoiding overhead irrigation, responsible usage of nitrogen fertiliser, weeding and application of adequate nutrients to your crops can reduce the chances of your cucumber plants having downy mildew.
However, the humid nature of Nigeria significantly increases the chances of getting this disease.
