Abstract

The invention relates to a pesticide composition containing benzothiostrobin and fluopyram. The ratio of benzothiostrobin to fluopyram in parts by weight is (1:30) to (30:1), and the balance is a pesticide adjuvant. The pesticide composition has a relatively good synergetic effect on prevention and treatment of powdery mildew of cucumber within a ratio range, and is beneficial to reduction of the usage amount of an active component of the pesticide and reduction of the medication cost.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and specifically relates to a pesticide composition containing penthiostrobin and fluopyram and its application. Background technique [0002] Cucumber powdery mildew, commonly known as "white hair disease", is the most serious damage to leaves, followed by petioles and stems, and generally does not harm fruits. In the early stage of the disease, small white nearly round powder spots appear on the front or back of the leaves, and gradually expand into large white powder areas with inconspicuous edges, covering the leaf surface, as if sprinkled with a layer of white powder. Wipe off the white powder, it can be seen that the leaves are chlorotic, withered and yellow and brittle. When the disease is severe, the leaves are covered with white powder and become off-white until the whole leaf dies. After powdery mildew infects petioles and tender stems, the symptoms are similar to those on the le...
