Embodiment 1

[0022] Embodiment 1, to the matching screening of rice brown planthopper

[0023] 1. Drugs for testing:

[0024] 70% Isoprocarb Technical (provided by Jiangxi Guixi Pesticide Factory); 65% Quetiafos EC (provided by Jiangxi Huifeng Pesticide Chemical Co., Ltd.);

[0025] 2. Proportion design:

[0026] Isoprocarb

[0027] Quetiaphos

[0028] Formula 1: Isoprocarb 6%, Quetiafos 18%; ratio 1:3.00

[0029] Formula 2: Isoprocarb 8%, Quetiafos 16%; ratio 1:2.00

[0030] Formula 3: Isoprocarb 10%, Quetiafos 14%; ratio 1:1.4

[0031] Formula 4: Isoprocarb 12%, Quetiafos 12%; ratio 1:1

[0032] Formula 5: Isoprocarb 14%, Quetiafos 10%; ratio 1:0.71

[0033] 3. Insects to be tested: 3rd to 4th instar nymphs of brown planthopper;

[0034] 4. Test method: refer to the agricultural industry standard NY / T 1154.7-2006 of the People's Republic of China and adopt the seedling soaking method. A co-toxicity coefficient greater than 120 indicates a synergistic effect; if the co-toxicity c...

Embodiment 2

[0056] Embodiment two, the field efficacy test to rice brown planthopper

[0057] In order to verify the control effect on brown planthopper, in October 2011, a field test of 24% isoprocarb-quinathion mixture (12+12%) was carried out on Zhongzao No. 1 during the lactation period.

[0058] 1. Types and dosages of field pesticide tests:

[0059] (1) 24% Isoprocarb·Quetiafos Mixture (12+12%) 100 grams per mu

[0060] (2) 20% isoprocarb emulsifiable oil per mu dosage 60 grams

[0061] (3) 25% Quetiafos EC: 60 grams per mu

[0062] (4) Blank control.

[0063]2. Method: Set up plots in the field and repeat four times. Before the medicine, 4 days and 10 days after the medicine, the pan pat was used to investigate the amount of adults, nymphs and spiders of the brown planthopper in each plot. Calculate the population reduction rate of N. lugens planthopper 4 days and 10 days after treatment, the control effect and the killing effect on spiders.

[0064] 3. The results a...

Abstract

The invention relates to an isoprocarb and quinalphos compound pesticide belonging to the technical field of compound pesticides. The isoprocarb and quinalphos compound pesticide comprises the following components in percentage by weight: 6-14 percent of isoprocarb and 10-18 percent of quinalphos. The isoprocarb and quinalphos compound pesticide has a cotoxicity coefficient of above 500, has a remarkable synergistic effect, is good in brown planthopper controlling effect of 89-100 percent and is good in quick-acting property and durability, the control effect can be above 90 percent after being applied for 10 days, the pesticide is low in use cost which is reduced by about 20-30 percent compared with the single-used quinalphos.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and in particular relates to compound pesticides of isoprocarb and quinathion. 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. According to the statistics of the agricultural department, due to diseases, insects, weeds and other hazards, the output loss reaches 20-30% every year. The amount of pesticides used to control rice diseases, insects, and weeds accounts for about 50% of the annual pesticide use in my country. The area under the treatment of rice pests in the country is about 1.2 billion mu per year, and the area under the treatment of pests will be even larger every year. [0003] Pesticides used to control major rice pests, such as rice leaf rollers, have used monosultap and chlorpyrifos for many years. In the past 3 to 5 years, abamectin, ...
