Embodiment 1

[0016] Example 1: Indoor Toxicity Test of Mixed Monosultap and Pyriproxyfen

[0017] Referring to NY / T 1154.14-2008 Insecticide Indoor Bioactivity Determination Method, rice leaf dipping and inoculation method was used for indoor synergistic bioactivity determination. Each treatment was repeated 4 times, and 10-15 rice thrips 2nd instar nymphs were used for each concentration treatment. First, after 48 hours of treatment, check the mortality rate of the test insects in each treatment, and calculate the corrected mortality rate, and use the probability value analysis method to calculate the toxicity regression equation and lethal intermediate concentration LC of each agent treatment 50 , according to Sun Yunpei's method to calculate drug mixing co-toxicity coefficient CTC.

[0018] Table 1 shows the toxicity test results of the mixture of monosultap and pyriproxyfen on rice thrips nymphs. As can be seen from the table, the co-toxicity coefficients of mixed medicaments are all ...

Embodiment 2

[0021] Embodiment 2: Two kinds of pesticide formulation tank mixing use stability

[0022] Table 2 Stability of tank mixing between two different formulations of pesticides

[0023]

[0024] It can be seen from Table 2 that the soluble powder (SP) and water agent (AS) with monosultap as the active ingredient can be mixed with the water emulsion (EW) and microemulsion (ME) with pyriproxyfen as the active ingredient. The water emulsion (EW) with monosultap as the active ingredient can be mixed with the emulsifiable concentrate (EC), water emulsion (EW) and microemulsion (ME) with pyriproxyfen as the active ingredient.

Embodiment 3

[0025] Embodiment 3: Monosultap and pyriproxyfen field tank mixing efficacy synergistic test

[0026] Select the group with the highest co-toxicity coefficient of monosultap and pyriproxyfen (ratio 6:1), and then carry out the field control test of tank-mixed pesticides on rice thrips in accordance with the guidelines for field efficacy tests of pesticides of the Ministry of Agriculture of my country ( The water consumption per mu is 45 kg), and the population reduction rate and corrected control effect are calculated according to the number of pests in the treatment area and the control area before and after spraying.

[0027] Table 3 Field control effect of monosultap and pyriproxyfen (6:1) field tank mix on rice thrips

[0028]

[0029] The control effects of monosultap and pyriproxyfen field tank mixing on rice thrips are shown in Table 3. It can be seen from Table 3 that the control effect after tank mixing is significant, reaching more than 85%, and the usage of activ...

Abstract

The invention discloses a synergic formula of field tank-mixed pesticide for rice pest control. The field tank-mixed pesticide is formed by mixing two pesticide preparations, and effective components of the two pesticide preparations are monosultap and pyriproxyfen respectively; the weight ratio of monosultap to pyriproxyfen is 3:9-1:3, and the optimal synergic ratio is 6:1. According to the field tank-mixed pesticide, the rapid poisoning effect of monosultap on adult pests and pest larvae (nymphs) and the sustained poisoning effect of pyriproxyfen on eggs and newly-hatched larvae (nymphs) are fully exerted, rice pests can be rapidly and efficiently killed to prevent incidence and damage, the field control effect can be significantly improved, and the safety of rice grain production can be ensured; besides, the pesticide usage amount and usage frequency can be effectively reduced, the control cost is lowered, and the production benefit is increased; meanwhile, pollution caused by pesticide to the paddy eco-environment is reduced, and thus the field tank-mixed pesticide has significant economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of agricultural diseases and insect pests, and in particular relates to a field tank-mixed pesticide synergistic formula for the prevention and control of rice pests. Background technique [0002] Monosultap, chemical name: 2-dimethylamino-1-sodium thiosulfonate-3-thiosulfonate propane, molecular formula C 5 h 12 NNa 2 o 6 S 4 , molecular weight 333.4016. Disultap is a kind of nereistoxin insecticide, which has gastric poisoning, contact killing and systemic conduction effects, and also has certain fumigation effect, and has good insecticidal activity against various agricultural pests. [0003] Pyriproxyfen, also known as pyriproxyfen, chemical name: 4-phenoxyphenyl (RS)-2-(2-pyridyloxy)propyl ether, molecular formula C 20 h 19 NO 3 , with a molecular weight of 321.3698, a phenyl ether insect growth regulator, is a juvenile hormone-type chitin synthesis inhibitor, with high...
