Peanuts must catch six points in the middle and late stages of high yield
Peanut cultivation during the growing season requires careful attention to pest and disease management, foliar nutrition, growth regulation, irrigation, timely harvesting, and post-harvest frost protection. Proper care at each stage ensures high yield and quality.
First, managing pests and diseases is crucial. Common issues include leaf spot, rust, aphids, and cotton bollworms. If left unchecked, these can lead to premature leaf drop and reduced photosynthetic activity. To control leaf spot and rust, apply fungicides such as carbendazim, thiophanate-methyl, mancozeb, or chlorothalonil through foliar sprays. Apply two to four times, with intervals of 10–15 days depending on disease severity. For pest control, if larvae are detected, use insecticides like methamidophos or phoxim. During hot and humid summer conditions, cotton bollworms may become more active. When infestation levels exceed thresholds, consider using newer bio-pesticides like *Proteobacterium*, "Insect Overlord," or "Thousand-thousands" for effective control.
Second, applying foliar fertilizers helps maintain leaf health and boost pod development. During the late stage of pod filling, spray leaves every 7–10 days with a solution containing nitrogen, phosphorus, potassium, and other essential nutrients. This not only sustains leaf vitality but also enhances pod size and fill.
Third, growth regulators should be used in the early stages of pod formation. Spraying paclobutrazol, *peanut-bamboo*, or *Zhuang-Shen-an* helps control plant height, maintain a dense leaf canopy, and improve nutrient transfer to developing pods. This promotes better photosynthesis and overall yield.
Fourth, watering is essential during the pod maturation phase. In case of drought, immediate irrigation is necessary to support healthy growth and ensure stable yields.
Fifth, timely harvesting is critical. Harvest peanuts 15 days before the first frost in early September, or within 4 days after the first frost but before the second. Avoid delaying harvest, as frost can damage the crop and reduce oil content and germination rates. After harvesting, spread the peanuts in the field for 7–10 days, turning them every three days to ensure moisture reaches around 9%. Do not store them immediately, as poor drying can lead to mold and spoilage.
Finally, frost protection is important after harvest. Frozen peanuts lose quality, oil content, and germination potential, leading to lower profits. Dry the harvested peanuts in the field for 7–10 days to reduce moisture to 9% or less. Avoid piling them up immediately, as this can cause mold and germination due to high humidity and temperature. Proper drying ensures better storage and market value.
