Embodiment Construction

[0017] The present invention is further illustrated below by way of examples. In the present invention, unless otherwise stated, all percentages are percentages by weight.

[0018] Formula 1: ivermectin 0.3%, pymetrozine 5.7%.

[0019] Formula 2: ivermectin 0.6%, pymetrozine 5.4%.

[0020] Formula three: ivermectin 0.9%, pymetrozine 5.1%.

[0021] Formula 4: ivermectin 1.2%, pymetrozine 4.8%.

[0022] Formula five: ivermectin 1.5%, pymetrozine 4.5%.

[0023] Formula six: ivermectin 1.0%, pymetrozine 4.0%.

[0024] Test 1. The compound pesticides of the above formula were used to determine the joint action of the rice leaf roller, and the tested insects were the 4th to 5th instar larvae of the rice leaf roller; the test method refers to the agricultural industry standard of the People's Republic of China NY / T1154.7- 2006, Insect soaking method. A co-toxicity coefficient greater than 120 indicates a synergistic effect; a co-toxicity coefficient less than 100 indicates an a...

Abstract

The invention relates to a pymetrozine and ivermectin mixed pesticide belonging to the technical field of mixed pesticides. The pymetrozine and ivermectin-mixed pesticide is characterized by containing the following components in percentage by weight: 1.0-30% of pymetrozine and 0.2-5.0% of ivermectin. The co-toxicity coefficient of the pymetrozine and ivermectin mixed pesticide reaches 1013-2292, and the pymetrozine and ivermectin mixed pesticide has the advantages of good effect for preventing and treating brown plant hoppers and cnaphalocrocis medinalis, favorable quick action and durability and low using cost, wherein the preventing and treating effect reaches 95%-100%, the preventing and treating effect can also reach over 90% after the pesticide is applied for 10 days; and the using cost reduced by about 30-40% as comparison with that of the pesticide only prepared from the pymetrozine.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, in particular to the compound pesticides of pymetrozine and ivermectin. Background technique [0002] Pymetrozine, English name: Pymetrozine, alias: pyrazinone, molecular formula: C 10 h 11 N 50 . Pymetrozine is a new type of non-destructive insecticide. Its preparations can be used to control most of the Homoptera pests, especially the pests of Aphididae, Whiteflyceae, Leafhoppers and Planthoppers. It is suitable for vegetables, ornamental plants and fruit trees. , citrus, rice, cotton and a variety of field crops, and can also control all important aphids on potatoes to control the occurrence of potato virus diseases. Its mode of action is unique, and it has no direct knockdown activity on pests. Once an insect comes into contact with the agent, it can immediately block the insect stylet and stop feeding. This process is irreversible. Before it dies due to stopping feeding Hand...
