In May, the weather is generally pleasant with gradually rising temperatures and significant day-to-night temperature differences. Occasional rain showers may occur, making the air relatively humid while the soil remains dry. This climate creates favorable conditions for the development and spread of common vegetable diseases, prompting farmers to remain vigilant.
For protected vegetables, especially solanaceous crops like tomatoes and peppers, issues such as blossom end rot, sunscald, soft rot, powdery mildew, and tomato leaf mold are frequently observed. In melon crops, powdery mildew, downy mildew, blossom end rot, and viral infections are also prevalent. To manage these diseases effectively, it's essential to combine proper agricultural practices with scientifically sound pesticide applications, along with timely foliar feeding and calcium supplementation using plant growth regulators.
In major vegetable-producing areas like Shouguang in our province, calcium deficiency in fruits during early summer is a common issue, often leading to reduced market value. Therefore, maintaining adequate calcium levels is crucial for crop quality.
Common pests in protected vegetables include Liriomyza sativae (leaf miner), whiteflies, tea green leafhoppers, spider mites, aphids, and thrips. It is recommended to use physical and biological control methods in greenhouses to manage these pests effectively.
In open-field vegetables, cabbage and sugar beets are often affected by the diamondback moth (Plutella xylostella) and the beet armyworm (Spodoptera exigua). At high temperatures, bio-insecticides like Bt (Bacillus thuringiensis) are effective for controlling these pests. For instance, 0.36% matrine water agent at 800 times dilution or 5% anti-Tai Bao at 1000 times, combined with 10% suspension agent (can be used alongside diamondback moth treatment) at 1500 times, or 15% DuPont Hit suspension agent at 3500–4500 times dilution can be applied.
In leguminous crops, bean pods are often plagued by spider mites, along with rust, leaf mold, powdery mildew, and downy mildew. On open-field melons and eggplants, the 28-spotted ladybug is a common pest that requires attention. Farmers should monitor their fields regularly and implement integrated pest management strategies to ensure healthy and productive crops.
