The invention discloses a plant pesticide for preventing and treating brachmia triannuella. The plant pesticide contains an extraction solution containing the following components in parts by weight: 15-20 parts of allium victorialis, 10-20 parts of centranthera cochinchinensis, 5-10 parts of linden viburnum, 5-10 parts of cryptomeria fortunei and 20-30 parts of leaves of elaeagnus pungens. By taking natural plants as main effective components, the use amount of the plant pesticide is small, and the decomposition speed is high, so that the environmental-pollution is avoided, and the plant pesticide has lower lactation toxicity than traditional pesticides.
Description
technical field [0001] The invention relates to a pesticide, in particular to a plant pesticide for preventing and controlling the sweet potato wheat moth. Background technique [0002] Sweet potato leaf roller, also known as sweet potato leaf roller, is a pest that spins silk and rolls leaves with larvae, and eats mesophyll in the rolled leaves to cause damage. It mainly damages sweet potatoes, water spinach and other Convolvulaceae plants. The sweet potato wheat moth has 3-4 generations in one year in our field, and the generations overlap. The insect overwinters as pupae in stumps and fallen leaves in the field. The wintering pupae begin to emerge in early June, and the larvae can be seen rolling leaves in the field in late June to cause damage. Mature larvae pupate and overwinter. Adults of the sweet potato moth have strong phototaxis and are active. They lurk in hidden places in the field during the day and mate and lay eggs at night. The eggs are usually scattered be...
