Embodiment 1

[0017] Bioassay Example 1: Indoor combined virulence test of the compound pair of diprofen and matrine on rice planthopper

[0018] Test object: Nilaparvata lugens (Stdl), the brown planthopper, artificially raised indoors for many generations.

[0019] Test method: The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.11-2008", using the rice stem soaking method. Pull out the robust rice plants at the end of tillering stage by rooting, wash them, and cut them into 15cm-long rooted rice stalks, 4 plants in groups, and dry them in the shade until there are no water marks on the surface. Soak the rice stems in the diluted medicament for 30 seconds. After they are taken out and air-dried, they are put into a petri dish with soaked absorbent cotton around the roots, and the mid-third instar nymphs are sucked into the petri dish, 25 per cup. Soak in clean water as a blank control, and repeat each concentration 4 times. After treatment, they ...

Embodiment 2

[0030] Bioassay Example 2: Indoor combined virulence determination test for thrips in combination of dipropiofen and matrine

[0031] Test object: Frankliniella occidentalis, the cucumber seedlings were artificially raised in an incubator for seven generations.

[0032] Test method: The test refers to the "People's Republic of China Agricultural Industry Standard NY / T 1154.14-2008" and uses the leaf immersion method to determine. Soak the prepared cabbage leaves (3㎝×4㎝) in the medicinal solution for 10 seconds, take it out and let it dry until there are no water marks on the surface, pick up the third instar nymphs of western flower thrips with a brush, and transfer the test insects Normally cultivate in a greenhouse at (25±1)°C, 14 / 10 (L / D), and a relative humidity of 70%. Each treatment was repeated 3 times, and each repeated 30 test insects.

[0033] The statistical analysis method is the same as that of Bioassay Example 1, and the virulence test results are shown in Table 2.

Embodiment 3

[0037] Bioassay Example 3: Indoor Joint Toxicity Determination Test of Bipropacyclone and Matrine in a Compound Pair of Green Leafhopper

[0038] Test object: Empoasca pirisuga (Matumura), a cabbage raised indoor for eight generations.

[0039] Test method: The test refers to the "People's Republic of China Agricultural Industry Standard NY / T 1154.14-2008" and uses the leaf immersion method to determine. Soak the prepared cabbage leaves (3㎝×4㎝) in the medicinal solution for 10 seconds, take it out and let it dry until there are no water marks on the surface, use a writing brush to pick up the adult green leafhoppers of the same age and put them into the insects. In the box, transfer to (25±1)°C, 14 / 10 (L / D), and normal culture in a greenhouse with a relative humidity of 70%. Each treatment was repeated 3 times, and 50 test insects were repeated every time. Check the number of dead insects at 72h, calculate the mortality rate and the corrected mortality rate. If the control morta...

Abstract

The invention discloses a synergistic insecticidal composition containing afidopyropen, wherein effective components of the synergistic insecticidal composition comprise afidopyropen and matrine with the mass ratio of 50:1-1:10, and the total mass content of the effective components in the composition is 3% to 65%. The composition can be made into a suspending agent, a suspension emulsion, a microemulsion, a water emulsion, a wettable powder, water dispersible granules or a microcapsule suspending agent which is allowed in agriculture. The synergistic insecticidal composition has reasonable components, has good effects on plant hopper, tea lesser leafhopper, thrips and other piercing-sucking type and rasping-sucking mouthpart pests on rice, tea leaves and vegetable crops; compared with a conventional single preparation, the synergistic insecticidal composition has significant insecticidal effects, has obvious synergistic effects, reduces the pesticide dosage, thereby reducing the cost and reducing pollution to the environment and facilitating governance for drug resistance of the pests; the synergistic insecticidal composition has great economic and social benefits in promotion and application.

Description

Technical field [0001] The invention relates to a synergistic insecticidal composition, in particular to a synergistic insecticidal composition containing diprofen and its application for preventing and controlling small pests on crops, belonging to the technical field of compound pesticides. Background technique [0002] Common small pests such as planthoppers, green tea leafhoppers, and thrips have the characteristics of wide host range, fast reproduction, a large number of annual generations, and resistance to pesticides. They cause large losses to agricultural production. At present, commonly used control agents such as chrysanthemum The esters of cypermethrin and lambda-cyhalothrin, and the neonicotinoids of imidacloprid, thiamethoxam and acetamiprid have developed higher resistance. Therefore, there is an urgent need for a high-efficiency and low-toxic agent for controlling small pests such as planthoppers, green leafhoppers and thrips. [0003] Diprofen, common name in Engl...
