Problems solved by technology

However, a large amount of abuse of abamectin has led to the emergence of drug resistance, so that farmers have increased the use of 1.8% abamectin per mu from 10 to 15 milliliters to the current 50 to 100 milliliters, or even 200ml per mu
Such a large amount of abuse has caused environmental pollution and harm to human beings

Embodiment 1

[0051] The preparation of embodiment 1 rose fume-colored Isyriamycetes powder

[0052] The I. fumigatus used in the examples of the present invention is I. fumigatus strain SCAU-IFCF02, which was deposited in the China Center for Type Culture Collection on November 1, 2013, with a preservation number of CCTCC NO: M 2013526.

[0053] The preparation process flow chart of the rose fume-colored I. spp. powder of the present invention is as attached figure 1 As shown, the specific method is as follows:

[0054] S1. Take the above-mentioned I. fumigatus strain SCAU-IFCF02, and under sterile conditions, take a ring with an inoculation loop and connect it to SDAY solid medium (a solid spore-forming medium commonly used in fungal culture) for activation. The photoperiod is light:dark=14:10, cultured in a constant temperature incubator at 24°C, and the best culture time is 15 days;

[0055] S2. Pour 10 mL of 0.03% Tween-80 sterile water onto the solid medium described in S1, wash ...

Embodiment 2

[0063] The preparation of embodiment 2 20% I. fumectinus and Abamectin oil suspension

[0064] 1. The preparation process flow chart is attached figure 2 As shown, the specific method is as follows:

[0065] S1. According to the formula requirements, add I. fumoscens powder, vegetable oil, and emulsifier into the mixing kettle, and stir in a high-shear emulsifier machine at 4000r / min for 10 to 15 minutes to fully mix the materials evenly;

[0066] S2. Add the mixed product of S1 to Abamectin original drug, stabilizer, suspending agent, dispersant and mineral oil or methyl oleate, continue high-shear emulsification in the mixing kettle, and stir at 4000r / min for 10 ~15min;

[0067] S3. Put the product obtained in S2 into a sand mill for sand milling to a particle size of 0.5-5 μm to obtain a fume-coloured I. spp. and avermectin oil suspension, which is measured and packaged to obtain a finished product.

[0068] 2. The 20% I. fumectin and avermectin oil suspension prepare...

Embodiment 3

[0069] Example 3 20% Preparation of oil suspension concentrate of I. fumoscens and abamectin

[0070] 1, preparation method: with embodiment 2.

[0071] 2. The 20% I. fumectin and avermectin oil suspension prepared in the present embodiment comprise the following components by weight percentage: I. fumectin powder 18%, abamectin 2%, and 18% soybean oil, 10% alkylphenol polyoxyethylene ether, 2% alkylphenol polyoxyethylene ether formaldehyde condensate sulfate, 3% epoxy linseed oil, 1% organic bentonite, 2% sodium alginate, methyl oleate Ester make up to 100%.

Abstract

The invention discloses an isaria fumosorosea and abamectin oil suspension agent as well as a preparation method and application of the isaria fumosorosea and abamectin oil suspension agent. The isaria fumosorosea and abamectin oil suspension agent comprises the following components in percentage by mass: 1-5 percent of abamectin, 1-20 percent of isaria fumosorosea fungus powder, 1-20 percent of vegetable oil, 3-15 percent of an emulsifier, 0.1-5 percent of a dispersant, 1-5 percent of a stabilizer, 1-5 percent of a suspending agent, and the balance of mineral oil or methyl oleate. The isaria fumosorosea and abamectin oil suspension agent disclosed by the invention is mainly used for preventing and treating insects including plutella xylostella, solenopsis invicta and the like, has the advantages of synergism, good permeability, high activity, stable effect, long effect lasting period, small environmental pollution, high adhesion, evaporation resistance and the like, also can be used for treating various crop insects, and has quite good application and popularization values.

Description

technical field [0001] The invention relates to a microbial oil suspension. More specifically, it relates to a kind of I. fumigatus and abamectin oil suspension, its preparation method and application. Background technique [0002] Rosy Rod Hug ( Isaria fumosorosea ) as a class of entomogenic fungi that can cause the death of pests are widely distributed all over the world and have a wide range of hosts. There are 25 different families of insects recorded, including some important agricultural Pests are species with great potential for development and application in biological control. I. fumigatus has strong pathogenicity and is safe to human, livestock, crops and the environment. It is one of the most widely studied and applied microbial insecticides. [0003] Because of its wide host range, strong prevalence, and safety to humans, animals and the environment, I. fumoscens has been used by researchers as the main means of pest control for a long time. However, the fungu...
