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: indoxacarb 0.3%, pyridazinate 17.7%.

[0019] Formula 2: indoxacarb 0.6%, pyridazinphos 17.4%.

[0020] Formula 3: indoxacarb 0.9%, pyridazinon 17.1%.

[0021] Formula 4: indoxacarb 1.2%, pyridazinphos 16.8%.

[0022] Formula five: indoxacarb 1.5%, pyridazinphos 16.5%.

[0023] Formula 6: indoxacarb 1.0%, pyridazinphos 17.0%.

[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 indic...

Abstract

The invention relates to an indoxacarb and pyridaphethione composite pesticide, belonging to the technical field of composite pesticides. The invention is characterized in that the indoxacarb and pyridaphethione composite pesticide contains the following components by weight percent: 0.2-10 percent of indoxacarb and 10-30 percent of pyridaphethione. The indoxacarb and pyridaphethione composite pesticide has the advantages that the insecticide controlling spectrum is wide and the quick action is good; the harm to the environment and the human body is small because the toxicity is low; and the production cost is low. According to the composite pesticide toxicity test conducted to rice leaf rollers, the co-toxicity coefficient reaches 245-410. According to the test of pesticide effectiveness, the indoxacarb and pyridaphethione composite pesticide has good effect on the prevention and the control of rice leaf rollers.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and in particular relates to a compound pesticide of indoxacarb and pyridazinate. Background technique [0002] Indoxacarb, molecular formula: C 22 h 17 CIF 3 N 3 o 7 , molecular weight 527.84. Toxicity: Indoxacarb is a low-toxicity insecticide, very safe to humans and animals; acute oral LD ​​in rats 50 5000 mg / kg; acute transdermal LD ​​in rabbits 50 Greater than 2000 mg / kg; no carcinogenic, teratogenic and mutagenic effects. Mechanism of action: Indoxacarb disables the function of nerve cells by blocking the sodium ion channels in insect nerve cells. [0003] Pyridazinthion, other names: Dajingsong Dajingsong, Bendafos. Performance: High-efficiency, low-toxicity, low-residue broad-spectrum organophosphorus insecticide. The pure product is white crystal with a melting point of 54.5-56.5°C. Stable to heat, light and acidic media, unstable in strong alkaline media. Insolubl...
