Abstract

The invention relates to the technical field of pesticides, in particular to a pesticide for preventing and treating rice sheath blight and a method for preparing the pesticide. The pesticide for preventing and treating the rice sheath blight comprises, by weight, 100-120 parts of erigeron annuus, 25-30 parts of hedera helix, 25-30 parts of rumex acetosa, 15-20 parts of herba leonuri, 10-15 partsof michelia alba, 10-15 parts of xanthium strumarium, 10-15 parts of radix phytolaccae and 5-8 parts of emulsifiers. The pesticide and the method have the advantages that the pesticide for preventingand treating the rice sheath blight is prepared by means of drying, extracting, preparing and concentrating and is convenient to operate; good effects of preventing and treating the sheath blight canbe realized by the prepared pesticide for preventing and treating the rice sheath blight; the pesticide is free of influence on normal growth of rice, and the pesticide and the method are environmentally friendly and safe and are high in efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of pesticides, in particular to a pesticide for preventing and treating rice sheath blight and a preparation method thereof. 【Background technique】 [0002] Sheath blight is a fungal disease caused by Rhizoctonia solani. It is one of the most common major diseases of rice. Generally, the early rice is heavier than the late rice, which often causes the grains to be not full, the empty shell rate increases, and the serious ones can cause the plants to fall and die. Common in grasses such as rice, wheat, and millet. The pathogen Thanatephorus cucumeris (Frank) Donk. is called the melon-destroyed bacterium, which belongs to the fungus of the Basidiomycotina subphylum. The asexual Rhizoctonia solani Kühn is called Rhizoctonia solani, a fungus belonging to the subphylum Deuteromycota. The main pathogenic hyphal fusion group is AG-1, which accounts for more than 95%, followed by AG-4 and AG-Bb (Sclerotinia dik...
