H.T 17:10 02/05/2020

(Baothanhhoa.vn) - Hiện nay, trên địa bàn tỉnh diện tích lúa đang trổ, phơi màu khoảng 63.000/115.158 ha, chiếm 54,2% diện tích. Lúa hiện đang bước vào giai đoạn cuối vụ, đây là thời điểm quyết định đến năng suất của toàn vụ. Tuy nhiên, những ngày qua, không khí lạnh kèm theo mưa ẩm kéo dài, xen kẽ những ngày nắng, nên là điều kiện thuận lợi để các đối tượng sâu bệnh phát sinh và gây hại nặng trên lúa, như: Bệnh đạo ôn cổ bông, bệnh đạo ôn lá, đen lép hạt, rầy nâu và rầy lưng trắng.
