Core Viewpoint - The recent Typhoon "Maidum" has significantly impacted rice production in the Guangdong province, particularly in the western region, where rice is in a critical growth stage. The typhoon has caused extensive damage, leading to substantial losses for farmers and raising concerns about future crop yields [3][4][5]. Impact on Rice Production - The typhoon made landfall on October 5, with maximum wind speeds reaching 14 levels (42 meters per second), causing severe flooding and crop lodging in rice fields [3][4][10]. - Many farmers reported that their rice crops, which were in the critical grain-filling stage, suffered over 50% yield loss due to lodging [10][11]. - The typhoon's impact was exacerbated by its strong winds, which were more damaging than previous storms, despite being classified at a lower level [18][21]. Recovery and Mitigation Strategies - Following the typhoon, farmers are beginning recovery efforts, focusing on pest and disease control due to increased risks from the storm [26][39]. - Recommendations for recovery include timely drainage of flooded fields and specific fertilization techniques to support damaged crops [33][37]. - Farmers are considering replanting with alternative crops, such as sweet corn, to mitigate losses [31][32]. Pest and Disease Management - The typhoon has heightened the risk of various diseases and pests, including bacterial blight and rice planthoppers, necessitating immediate and effective pest control measures [38][39]. - Experts recommend using specific fungicides and bactericides to combat the anticipated outbreaks following the storm [40].
