preparation example Construction

[0029] In a preferred embodiment, the preparation method of the diatomite-Metarrhizia anisopliae pesticide composition comprises the following steps: mixing Metarhizium anisopliae and zigzag diatomite, in order to avoid destroying the zigzag diatomite The structure does not use mechanical crushing, shake it with a ziplock bag, transfer it to a flask after 10 minutes, stir and mix it with a stirrer for 30 minutes, and mix it evenly.

[0030] In a preferred embodiment, the dosage form of the diatomite-metarrhizia pesticide composition is selected from powder, wettable powder, emulsifiable concentrate, granule, bait, oil dispersion, oil suspension, water suspension, At least one of impregnating agent and ultra-low capacity agent.

[0031] The second aspect of the present invention provides a diatomite-metarrhizia wettable powder, its preparation raw materials include the above-mentioned diatomaceous earth-metarrhizia pesticide composition, including 100-120 parts by weight of sil...

Embodiment 1

[0052] Example 1. Co-toxicity coefficient method (CTC) screening: joint toxicity determination of diatomaceous earth-metarrhizia pesticide composition to citrus spider mite.

[0053] Referring to the method in the NY / T1154.13-2008 standard, the blade spray method is adopted. Wash and dry flat citrus leaves of the same size, put the leaves on the wet sponge with the leaf facing up, surround the leaves with a small wet cotton sliver to prevent the test mites from escaping, and put the wet sponge into the 9cm diameter In a petri dish, add water to the petri dish, the water level is slightly lower than the sponge height. Inoculate the leaves with indoor raised nymphs, no less than 30 per leaf. Place the petri dish in the chassis of the Potter spray tower for spraying, the spraying amount is 1mL, take out the medicine solution after settling for 1min, and transfer it to feeding conditions. Each treatment was repeated 4 times, and a blank control was set.

[0054] After 5 days, c...

Embodiment 2

[0061] Example 2. Co-toxicity coefficient method (CTC) screening: joint toxicity determination of diatomaceous earth-Metarhizium anisopliae pesticide composition on citrus scale insects.

[0062] Referring to the method in the NY / T1154.6-2006 standard, the insect soaking method is used. After finishing, the citrus leaves with the citrus scorpion were immersed in the test liquid for 10 seconds, then taken out, and the excess liquid around the leaves and worms was sucked off with filter paper, and put into a petri dish (diameter 90mm) with a moisture-retaining filter paper pad. ), the petiole was wrapped with wet cotton balls to keep moisture, and each concentration was repeated 4 times. After the treatment, the dish was covered and placed in the observation room for cultivation.

[0063] After 5 days, the death of the test insects was checked with a dissecting microscope and recorded. The criterion for judging the death of the test insects was that the color was fresh and alive...

Abstract

The invention relates to the technical field of pesticides, in particular to a diatomite-Metarhizium anisopliae pesticide composition and application thereof. According to the invention, the diatomite-Metarhizium anisopliae pesticide composition is prepared by compounding diatomite with a specific zigzag structure and Metarhizium anisopliae; the prepared pesticide composition is relatively good inpesticide effect and relatively wide in insecticidal range, and has relatively good pesticide effects on various pests such as citrus red spiders, citrus scale insects, frankliniella occidentalis, whiteflies, liriomyza sativae, prodenia litura, tea lesser leafhoppers, tea yellow thrips, tea geometrids, apolygus lucorum and grape aphids. Besides, the diatomite-Metarhizium anisopliae wettable powder is further prepared from a specific wetting agent and a dispersing agent, and the prepared diatomite-Metarhizium anisopliae wettable powder is good in wettability and spreadability, high in suspension rate and short in wetting time.

Description

technical field [0001] The invention relates to the technical field of pesticides, more specifically, the invention relates to a diatomaceous earth-metarrhizia pesticide composition and its application. Background technique [0002] Pests and diseases cause astonishing losses to agricultural production every year. In order to ensure stable and high yields of crops, chemical pesticide-based control measures have been used for a long time. However, with the improvement of the level of science and technology, people have gradually realized the safety of chemical pesticides on food and the environment, and then biological pesticides have achieved steady development. Microbial pesticides are one of the most important components of biological pesticides. The use of microbial pesticides can naturally restrict the population of pests and maintain ecological balance; at the same time, it can reduce the amount of chemical pesticides and greatly reduce the residues of chemical pesticid...
