The
strawberry mite
(Phytonemus pallidus), or
cyclamen mite
, is a microscopic, translucent pest that hides deep inside the crown of strawberry plants to avoid sunlight. Because it is invisible to the naked eye, you will only notice it by the damage it causes. It sucks the plant's sap and injects toxins, causing young leaves to emerge tightly wrinkled, stunted, and brittle. The entire plant become

Apple scab.
In this case, the preventive disease control strategy was insufficient, resulting in severe symptoms on the leaves. However, a timely eradicant treatment with
difenoconazole
successfully stopped further disease development. The canopy was then protected with a
captan
-based fungicide to reduce the risk of new infections.
The leaves still show the symptoms caused by the initial infec

Latent downy mildew on grape berries
Latent downy mildew is one of the most challenging forms of the disease to identify. As grape berries mature, their stomata become non-functional, preventing the pathogen from producing the characteristic white sporulation. Instead, infected berries gradually turn brown, shrivel and dry out, often making diagnosis more difficult.

Severe iron chlorosis on strawberry.
Apply a chelated iron fertiliser (preferably EDDHA for alkaline soils or EDTA for acidic to neutral substrates), either as a soil application or as a foliar spray, to restore iron availability. Check and correct the substrate or soil pH, avoid excessive irrigation, and monitor new leaf growth over the following 2–3 weeks, as existing chlorotic leaves are unlike

The images show poor fruit set in tomato plants. The flowers turn yellow, dry out, and eventually drop without developing into fruit. In this specific case, the problem is attributable to the absence of pollinating insects. However, the same symptoms can also be caused by excessively high temperatures, suboptimal relative humidity, poor air circulation, and, more generally, environmental condit
