Embodiment 1

[0024] To produce 1000kg of Ascospora platinae oil with a spore content of 3.2 billion per gram, 320kg of pure spore powder of Ascospora platinospores with a spore content of 100 million per gram, 380kg of soybean salad oil, and Span-80 Emulsifier 40kg, diatomaceous earth 160kg, ferric oxide 60kg, vitamin C 40kg.

[0025] Firstly, the pure spore powder of Ascospora platinae, diatomaceous earth, ferric oxide and vitamin C are added in batches to the No. 1 mixer and mixed evenly, and then pulverized by an airflow mill to obtain a mixture 1 with a particle size of less than 10 μm; the soybean Mix salad oil and Span-80 in the No. 2 mixer according to the mass ratio and stir evenly to obtain mixture 2; slowly add mixture 1 to mixture 2, and stir evenly in the colloid mill until the mixture becomes a reddish-brown paste. It is an oil agent of Ascospora sp.

[0026] When applying in the field, use 10g of Septoria platinosa oil per mu, mix with 30kg of water or 30kg of a mixed soluti...

Embodiment 2

[0028] The production of 1000kg spore content is 4 billion / gram Ascospora oil agent, and the raw material needs to contain 400 kg of Ascospora pure spore powder with spore content of 100 million / gram, 400 kg of soybean salad oil, 30 kg of Span-80 emulsifier, Diatomaceous earth 100kg, ferric oxide 40kg, vitamin C 30kg.

[0029] Concrete operation is as above-mentioned embodiment 1.

[0030] When applying in the field, use 4 billion / gram of Ascospora oil agent 10g per mu, mix with 40kg of water or 40kg of mixed solution containing 10% of the conventional field dosage of nitenpyram, and spray for application.

Embodiment 3

[0031] Example 3: Toxicity test of an oil agent of Ascospora sp. combined with nitenpyram on Bemisia tabaci.

[0032] The tested Bemisia tabaci were collected from vegetable fields, and were raised on tomato plants at room temperature (25±2°C) in the laboratory. Before inoculation, the leaf cover of the tomato plants to be tested was cleared, and the plants were removed 12 hours after inoculation, the adult insects were removed, and marks were made. Control the spawning density to 30-60 per leaf for biological assay. After inoculation, the growth time was controlled, and 2nd instar larvae were obtained for determination. Nitenpyram was made into a solution according to the conventional dosage in the field for use; the Ascospora oil agent stored in the refrigerator at 4 ° C was prepared according to the approximate concentration of the spores contained in it, and the spore content was 10 6 , 10 7 , 10 8 spores / ml suspension for use. After calculation, the nitenpyram soluti...

Abstract

The invention relates to aschersonia oil and compounded insecticide containing same and nitenpyram. The aschersonia oil includes, by weight, from 30 to 50% of aschersonia pure spore powder, from 15 to 40% of solvent oil, from 2 to 20% of food-grade emulsifying agent, from 2 to 40% of adsorbent, from 2 to 20% of ultraviolet absorbent and from 2 to 20% of antioxidant. The oil can prolong the storage period of spore and increase absorptivity of the spore. The aschersonia preparation can be used independently, can also be used with other chemical insecticides, and has the advantage of high insecticide ability when used with the nitenpyram. The aschersonia oil is diluted by nitenpyram aqueous solution, and the dosage of the nitenpyram does not exceed 10% of conventional dosage of the nitenpyram used in fields. The preparation method is simple, and a product has quite high effect of killing injurious insects including aleyrodid, aphid and the like, and plays an important role in preventing and killing farming and forestry pests.

Description

technical field [0001] The invention relates to an oil agent of Ascospora and its compound insecticide with nitenpyram. Background technique [0002] There are more than 100 genera and more than 1000 species of entomogenic fungi recorded and reported in the world. Among them, the entomogenic fungi of parasitic whitefly pests mainly include Beauveria bassiana, Paecilomyces rosea, Trichosporum tompsonii, Verticillium lecanii, Entomomyceles, and Septoria, mainly distributed in the generalized ergot fungi. division. At present, based on the production of pathogenic fungi such as Beauveria bassiana, Paecilomyces rosea, and Verticillium lecanii, there are relatively many studies on preparations and applications. Some studies have shown that the control potential of these entomogenic fungi on whitefly pests Can not be ignored. Ascospora ( Aschersonia sp.) can infect whiteflies and form epidemics, and play an important role in the natural control of whiteflies, and Ascospora is ...
