Wheat bunt

Infected (bunted) heads are slender and remain green longer than healthy heads. The glumes are opened either on some or on all spikelets, showing the bunt [...] Tilletia tritici and Tilletia laevis survive as teliospores in the soil or on seed. These teliospores germinate in response to moisture and form basidiospores [...] General Tilletia tritici and Tilletia laevis only differ in one gene and easily hybridize. There is debate whether they should indeed be considered separate

Mealybugs and scales

Biological control of mealybugs and scales Mealybugs and scale insects are persistent pests that feed on plant sap, weakening crops and producing honeydew that [...] beetles and lacewings help reduce mealybug and scale populations by attacking both larvae and adults. Pheromone traps support early detection and population [...] wingless and immobile, and covered with a hard scale (armoured scales and soft scales) or with waxy threads (mealybugs). They suck the sap of plants and are

Pumpkin, squash and gourd

The fruits of the Cucurbita species are usually large and fleshy, but their size can vary [...] are indigenous to the Andes region and Mesoamerica. Currently, five species are cultivated for their edible fruit and seeds. This fruit is alternately known [...] substantially. Wild fruit species can be as small as 4 centimetres (1.6 inch) and some commercial specimens can weigh more than 300 kilograms (660 lbs).

Crop Monitoring and Scouting

monitoring and scouting In the world of agriculture and horticulture, the phrase "knowledge is power" couldn't be truer. Crop monitoring and scouting are [...] insights into the health and growth of their crops, enabling them to take proactive measures and optimise their yield. Crop monitoring and scouting is the systematic [...] as sticky traps and pheromones, growers can promptly detect the presence of pests and respond accordingly. Benefits of crop monitoring and scouting One of

Pea blight, leaf and pod spot

symptoms Ascochyta pisi causes spots on leaves, stems and pods of peas. The spots on leaves and pods are round, on the stems they are more elongated. The lesions [...] that causes A scochyta blight on pea (leaf blight or pea blight) and lesions of stems, leaves, and pods (pea leaf spot and pea pod spot). Damage symptoms [...] brown, sunken and surrounded by a dark brown to red-brown border. The first infection is often on the primary leaves. The fungus is seed borne and thus also
