Embodiment Construction

[0016] The present invention is further illustrated below by way of examples. In the present invention, unless otherwise stated, all percentages are percentages by weight.

[0017] Formula 1: indoxacarb 0.6%, secbucarb 41.4%.

[0018] Formula 2: indoxacarb 0.9%, secbucarb 41.1%.

[0019] Formula 3: Indoxacarb 1.2%, Zhongbucarb 40.8%.

[0020] Formula 4: Indoxacarb 1.5%, Zhongbucarb 40.5%.

[0021] Formula 5: indoxacarb 1.8%, secbucarb 40.2%.

[0022] Formula 6: Indoxacarb 1.0%, Zhongbucarb 41.0%.

[0023] 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 antagonist...

Abstract

The invention relates to an indoxacarb and fenobucarb compound pesticide, which belongs to the technical field of compound pesticides and comprises the following components in percentage by weight: 0.6%-2% of indoxacarb and 38%-40% of fenobucarb. The co-toxicity coefficient of the indoxacarb and fenobucarb compound pesticide reaches 197 to 410, the effect on controlling cnaphalocrocismedinalis isgood, the control efficiency is 95 to 100 percent, the quick action and the persistence are good, the control efficiency can reach more than 90 percent after the pesticide is applied for 10 days, andthe decrease rate of live pests of the pesticide is higher than that of two separate agents.

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 secbutacarb for preventing and treating rice leaf rollers. Background technique [0002] Rice is the main variety of food crops in my country, with a large planting area, many types of diseases, insects, and weeds, and the damage is serious. Rice leaf roller is one of the main pests of rice in my country, and it occurs more seriously all year round. Especially in recent years, in East China and Jianghuai rice areas, from July to September, the peak of insect population overlaps continuously, and common pesticides are used for control 4-5 times If the control is not good, it will have a great impact on the growth of rice. Commonly used pesticides include dimehypo, monosultap, chlorpyrifos and avermectin, etc. However, for the control of older larvae, since the larvae hide in the rolled leaves, it is difficult for the l...
