Due to the heavy rainy weather in summer and the high temperature difference between day and night in the high-temperature county, it is suitable for the occurrence and prevalence of common diseases and insect pests of various vegetables. Therefore, the vegetable farmers were reminded to pay attention to the following diseases and insect pests.
First, the protection of vegetables: eggplant vegetables have umbilical rot, sunburn, rot, powdery mildew, leaf mold. Melon vegetables have powdery mildew, downy mildew, umbilical mildew, viral diseases, and so on. To prevent and treat these diseases, in addition to strengthening various agricultural management, we must also conduct scientific and reasonable chemical control, and at the same time cooperate with the spraying of foliar fertilizers, plant growth regulators and other timely calcium supplements. The phenomenon is not uncommon. Common pests of vegetables in protected areas include Liriomyza sativae Blanchi, Whitefly, Tetranychus urticae, Red spider, Aphid, Thrips, etc. It is recommended that vegetables in protected areas be controlled by physical and biological methods to prevent and control the above pests.
Second, the open field vegetables: large and small cabbage diamondback moth, beet liquid moth, Spodoptera litura widespread. Plutella xylostella is better at using Bt and other biological pesticides at high temperatures. Spodoptera exigua and Spodoptera litura can use 0.36% of matrine aqueous solution 800 times, or 5% of the inhibitor, or 10% of the total suspension. The agent (may co-treat the diamondback moth) is 1500 times liquid, or 15% of the Dupont hitting agent 3500-4500 times for spray control. Legumes, bean pods, and spider mites are more serious, with rust, leaf mold, powdery mildew, downy mildew, and mixed diseases. Eggplants and eggplants are prone to eggplant ladybirds.
