Embodiment 1

[0015] Embodiment 1, a kind of insecticidal composition, comprises following composition: emamectin 2.5%, dipropetal 5%, cyclohexanone 10%, emulsifier 16%, antioxidant 1%, water margin;

[0016] The preparation method of described a kind of insecticidal composition, comprises the steps:

[0017] Step 1: dissolving emamectin and dipropyraldin with cyclohexanone;

[0018] Step 2: Add antioxidants to the product of step 1, mix and stir until uniform and transparent;

[0019] Step 3: Add the emulsifier to the product of step 2, then add water, mix and stir evenly to prepare a microemulsion insecticidal composition composed of 7.5% emamectin and dipropetal.

[0020] When using, dilute 7.5% emamectin and dipropterate microemulsion by 2500 times with water, and use it as a spray. It has special effects on aphid control. The control effects of 1 day, 7 days and 15 days after the drug are 88.4 %, 97.6% and 94.9%. Using 5% emamectin and dipropterate single agent, after the same dilu...

Embodiment 2

[0021] Embodiment two: a kind of insecticidal composition, comprises following composition: emamectin 3%, dipropetal 30%, phosphate ester 6%, xanthan gum 0.16%, preservative 0.4%, antiseptic Oxidant 1%, water balance;

[0022] The preparation method of described a kind of insecticidal composition, comprises the steps:

[0023] Step 1: Pour water into the stirring tank, then add phosphoric acid ester, emamectin, dipropane, xanthan gum, preservatives and antioxidants in turn and shear and stir for 30 minutes;

[0024] Step 2: use 3 sand mills to sand-mill the product of step 1 in series to prepare a suspension-type insecticidal composition composed of 33% emamectin and dipropacyclopyrene.

[0025] When using, dilute 33% emamectin and dipropterate with 5000 times of water and use it by spraying. It has special effects on the control of thrips. The control effects of 1 day, 7 days and 15 days after the drug are 90.4% respectively. , 98.6% and 96.3%. Use 5% emamectin and diprope...

Embodiment 3

[0026] Embodiment 3, a kind of insecticidal composition, comprises the following composition: emamectin 2%, dipropetal 10%, emulsifier 18%, organic soil 2%, antioxidant 1%, methyl ester The remaining amount of vegetable oil;

[0027] The preparation method of described a kind of insecticidal composition, comprises the steps:

[0028] Step 1: Pour methylated vegetable oil into a stirring tank, add emulsifier, emamectin, dipropetal, organic soil and antioxidant in turn and shear and stir for 30 minutes;

[0029] Step 2: use three sand mills to sand-mill the product of step 1 in series, and then a suspension-type insecticidal composition composed of 12% emamectin and dipropacyclopyrene can be prepared.

[0030] When using, dilute 12% emamectin and dipropterate suspensible concentrate by 2000 times with water, and use it as a spray, which has special effects on whitefly prevention. The control effects of 1 day, 7 days and 15 days after the medicine are respectively 92.4%, 96.6% ...

Abstract

The invention discloses an insecticidal composition. The composition comprises emamectin and afidopyropen, a weight ratio of emamectin to afidopyropen is (1-30):(30-1), and preferably (1-10):(10-1). The insecticidal composition is a pesticide allowable dosage prepared by adding a pesticide assistant to the emamectin and afidopyropen, and includes, but not limited to, missible oil, a suspending agent, a suspoemulsion, a wettable powder, an emulsion in water, a microemulsion, a water dispersible granule, an oil suspension and a seed coating. Compared with single agents, the composition of the invention has the following advantages: the composition has a remarkable synergistic effect on piercing-sucking pests, so the application effect is improved; the field dosage is greatly reduced, so theuse cost is reduced, and environmental pollution and pesticide residues are reduced; and the completely different action mechanisms of the two effective components in the composition are beneficial toovercoming the generation of pesticide resistance of pests and are beneficial to control of resistant pests.

Description

technical field [0001] The invention belongs to the technical field of preparation of agricultural insecticides, and specifically relates to an insecticidal composition compounded with emamectin and dipropyrin. Background technique [0002] For a long time, piercing-sucking mouthparts pests have been a difficult point in agricultural control. At the same time, due to the single action site of the pesticide and the unscientific use of pesticides, it has a high resistance to the currently used chemical pesticides. Frequent and large-scale application of pesticides increases production costs and aggravates environmental pollution. Therefore, agricultural production urgently needs new varieties with high efficiency, low toxicity and environmental friendliness, so we propose an insecticidal composition. Contents of the invention [0003] The object of the present invention is to provide an insecticidal composition in order to solve the problem of non-standard pesticides for co...
