Key tips to protect crops from the heatwave in Chile

Farmers in central and south-central Chile are being advised to prepare for several days of heat above 30°C. Specialists from INIA Quilamapu recommend keeping soil moisture high, shielding fruit trees, and avoiding outdoor tasks during the hottest hours.

Agroclimatologist Raúl Orrego explained that the regions of Ñuble and Biobío could see temperatures between 29°C and 31°C next week — high enough to cause heat stress in crops, vegetables and greenhouses. He noted that when temperatures stay above 27.5°C for over three days in the central valley, it is classified as a heatwave.

To protect crops, Orrego suggests maintaining regular irrigation, improving airflow in greenhouses, and using shade nets. For workers, he stressed the need for hydration, sun protection, and avoiding peak-sun periods.

INIA specialist Jorge Retamal highlighted that fruit trees are especially sensitive to heat. He advised keeping irrigation steady and applying protective “sunblock” sprays every two weeks to prevent leaf damage and maintain yields.

Orrego also warned that lush vegetation will soon dry out and act as fuel, raising the risk of fires in grasslands, scrub and forest areas. He urged farmers to reduce combustible material, maintain firebreaks, and avoid activities that could spark fires during high-temperature days.
