Embodiment 1

[0017]The test object is the third instar larvae of the tenth generation of Spodoptera litura. The test agent is Metarhizium anisopliae, tetracloran, and a mixture of Metarhizium anisopliae and tetraclosan. The content of Metarhizium anisopliae is 20 billion spores / g, and the content of tetracloran is 95% of the original drug.

[0018]The test method refers to the pesticide NY / T 1154.7-2006, the agricultural industry standard of the People's Republic of China, "Pesticide Indoor Bioassay Test Guidelines", and the test adopts the larva dipping method. Soak the fresh leaves in the prepared medicinal solution for 10 seconds, take them out and dry in the shade. Place it in a petri dish containing moisturizing filter paper for feeding test insects. Treat the blank control first, and then repeat the above operations in the order of the designed dose of the experiment from low to high, repeating 4 times for each treatment. Put the larvae raised indoors into an insect dip, and prepare for the d...

Embodiment 2

[0037]A kind of suspending agent, calculated by weight percentage, including 20 billion spores / gram of Metarhizium anisopliae spore powder 26%, tetraclosan 1%, sodium lignin sulfonate 8%, tristyryl phenol polyether phosphate 600P 6%, xanthan gum 6%, epoxy soybean oil 3%, silicone oil 3%, propylene glycol 5%, ethyl acetate 4%, water to make up the balance to 100%.

[0038]Tristyryl phenol polyether phosphate 600P was purchased from Nantong Xitai Chemical Co., Ltd.

[0039]The preparation method of the suspending agent includes the following steps: mixing the components uniformly and pulverizing in a ball mill for 4 hours to form a coarse dispersion, adjusting the pH value to 7, and then superfine wet grinding to control the particle size D90≤5μm, You can get the suspending agent.

Embodiment 3

[0041]A suspending agent, calculated as a percentage by weight, including 20 billion spores / gram of Metarhizium anisopliae spore powder 16%, tetraclosan 1%, sodium lignin sulfonate 7%, tristyryl phenol polyether phosphate 600P 5%, xanthan gum 5%, epoxidized soybean oil 1%, silicone oil 2%, propylene glycol 5%, ethyl acetate 4%, water to make up the balance to 100%.

[0042]The preparation method of the suspension is the same as in Example 2.

Abstract

The invention provides an insecticidal composition for preventing and treating cymbidium sinense, the effective components of the insecticidal composition are metarhizium anisopliae and tetrachlorantraniliprole, and the ratio of the number of conidia of metarhizium anisopliae to the gram number of tetrachlorantraniliprole is (26-1) * 2 billion: (1-5). The metarhizium anisopliae and the tetrachlorantraniliprole are compounded to achieve a remarkable synergistic effect, the control effect is very good, the use amount of chemical pesticides can be reduced, and environmental pollution is reduced.

Description

Technical field[0001]The invention belongs to the technical field of pesticides, and specifically relates to an insecticidal composition for preventing and controlling Spodoptera litura.Background technique[0002]Laphygma SP. (Laphygma SP.) belongs to the Lepidoptera and Noctuidae family. It mainly harms Laphygma, Hippeastrum, Lycoris and other plants. It was first seen in India, Japan and other countries, and rarely occurred in my country. In recent years, with the increase in the number and area of ​​scallion used for landscaping, the range of occurrence of this insect is also expanding. When scallion moth is severe, it can eat all the stems of scallion. Although the stems and leaves of the green onion can still germinate and grow without causing the death of the green onion after the stems and leaves of the green onion are eaten by this insect, its growth potential is significantly weakened, and the impact on the landscape of the onion is also increasingly apparent, and the garden...
