In July this year, Yantai City experienced an average rainfall of 467.1 mm, which was 305.1 mm above the normal level. Meanwhile, sunshine hours ranged between 76 and 150 hours, a decrease of 67 to 110 hours compared to the same period last year. July is a critical growth stage for peanuts in Yantai, specifically the period when plants begin to develop pods and set flowers. This phase is essential for yield formation. However, prolonged rainy weather has led to excessive growth in peanut fields, which can negatively impact flower production, pod development, and overall yield.
Recent field surveys have identified several key issues affecting peanut growth in the city. First, most peanut plants have grown taller than 50 cm, with widespread elongation. If not controlled, this can lead to lodging later on, significantly reducing harvest. Second, there is uneven development of peanut pods, often due to insufficient light and poor nutrient absorption after the pegs are embedded in the soil. This can result in underdeveloped pods and lower economic returns. Third, some fields show lighter leaf color, likely due to root damage or early-stage nutrient deficiencies. Without proper nutrients, leaves may fall prematurely, leading to plant senescence. Lastly, the incidence of leaf spot diseases has increased, posing a serious threat to crop health.
To address these challenges, several measures are recommended. First, continued field drainage is essential. Improving the drainage system will help prevent waterlogging, especially in areas affected by heavy rain. Second, chemical control should be prioritized. For example, applying 40–50 g (2.0–2.5 g active ingredient) per mu or 20–25 g per acre mixed with 35–40 kg of water for foliar application can help manage pests and diseases effectively. Spraying should be done evenly, avoiding over-application or missed spots.
Third, timely prevention and control of pests and diseases are crucial. After heavy rains, high humidity and warm temperatures can promote the spread of diseases such as rhizome rot, leaf spot, and rust. Using appropriate fungicides like carbendazim at 200–300 times dilution or chlorothalonil at 600–700 times dilution can help control these issues. For underground pests, insecticidal lamps are recommended where possible, while chemical options include 48% chlorpyrifos at 250–300 ml per mu or 50% phoxim granules at 0.3–0.4 kg per mu. These should be diluted and applied carefully to the roots.
Finally, foliar topdressing combined with disease prevention can help delay premature aging. Applying a mixture of potassium dihydrogen phosphate, urea, and chlorothalonil via foliar spray every 10–15 days can extend leaf life and reduce the occurrence of leaf spot diseases. This approach supports both plant health and productivity.
