Chilli and papaya are important horticultural crops widely cultivated in tropical and subtropical regions due to their high nutritional and economic value. Chilli (Capsicum annuum L.) grows well in a warm and moderately humid environment with an optimum temperature range of 18–30 °C. It can be cultivated in both kharif and rabi seasons, depending on irrigation availability. Chilli prefers well-drained loamy or sandy-loam soils rich in organic matter with a slightly acidic to neutral pH (6.0–7.0). Good agronomic practices and balanced fertilization contribute to high productivity. However, chilli production is often affected by diseases such as leaf curl, anthracnose, powdery mildew, and damping-off, which can be managed through resistant varieties, proper field sanitation, crop rotation, and timely application of fungicides and insecticides.
Papaya (Carica papaya L.) is a fast-growing fruit crop that thrives in a warm climate with an ideal temperature range of 22–35 °C and is highly sensitive to frost and waterlogging. It can be planted almost year-round in tropical regions, with spring and early monsoon seasons being most favorable. Papaya grows best in well-drained sandy-loam soils rich in organic matter with a pH of 6.0–6.5. Under suitable environmental and soil conditions, papaya provides high yields within a short period. Major diseases such as papaya ringspot virus, leaf curl, root rot, and powdery mildew significantly reduce production, but effective disease management through healthy planting material, vector control, proper drainage, and integrated disease management practices helps maintain yield and fruit quality.

涉及作物：辣椒与番木瓜。其中辣椒病害涵盖卷叶病、尾孢叶斑病、细菌性斑点病、白斑病、营养缺素症，同时包含健康植株样本；番木瓜病害涵盖炭疽病、细菌性斑点病、卷叶病、环斑病，同时包含健康植株样本。
专家级真实标注信息涵盖土壤健康状况、湿度、营养缺素情况以及病理报告，该标注已由斋浦尔杜尔加普拉拉贾斯坦邦农业研究所（RARI）的普拉蒂巴·辛格博士审核验证。

辣椒与番木瓜均为重要的园艺作物，因兼具高营养价值与经济价值，在热带、亚热带地区广泛种植。辣椒（*Capsicum annuum* L.）适宜在温暖且湿度适中的环境中生长，最适温度区间为18~30℃。根据灌溉条件差异，辣椒可在卡里夫季（雨季作物季）与拉比季（旱季作物季）两季种植。其偏好富含有机质、排水良好的壤土或砂壤土，pH值范围为6.0~7.0（微酸性至中性）。良好的农艺措施与平衡施肥有助于实现高产。但辣椒生产常受卷叶病、炭疽病、白粉病以及猝倒病等病害侵扰，可通过种植抗病品种、落实田间清洁措施、实施作物轮作以及适时喷施杀菌剂与杀虫剂进行有效防控。

番木瓜（*Carica papaya* L.）为速生果树，适宜温暖气候生长，理想温度区间为22~35℃，对霜冻与涝害极为敏感。在热带地区几乎可全年种植，春季与季风初期为最佳种植时段。番木瓜最适宜生长在富含有机质、排水良好的砂壤土中，pH值范围为6.0~6.5。在适宜的环境与土壤条件下，番木瓜可在较短周期内实现高产。主要病害如番木瓜环斑病毒病、卷叶病、根腐病以及白粉病会大幅降低产量，但通过使用健康种苗、防控传毒媒介、完善排水措施以及采用综合病害管理方案，可有效维持产量与果实品质。
