AI Technical Summary

Problems solved by technology

[0007] The flash point is too low, and the ultra-low volume spray is more dangerous;
[0008] High volatility, poor droplet settling, when spraying with ultra-low volume, the droplets will drift for a long distance and cannot settle in the target area;
[0009] The speed of killing insects is slow, it is not easy to be accepted by the masses, and it is difficult to promote in a large area
[0010] easy to cause drug injury;
[0011] It has a certain peculiar smell and has a repellent effect on pests, especially pine leaf-eating pests (currently Beauveria bassiana is mainly used to control pine leaf-eating pests in my country), and will cause pests to refuse to eat

Embodiment 1

[0032] Take the spore content as 1.1×10 11 110 kilograms of Beauveria bassiana pure spore powder with a spore / g and live spore rate greater than 80%; 100 kilograms of sodium dodecylbenzenesulfonate; 100 kilograms of turpentine oil (chemically pure grade); 1800 kilograms of ethylene glycol (industrial pure grade) kg; 0.2 kg of ferric oxide; 5 kg of deltamethrin.

[0033] Mix the pure spore powder of Beauveria bassiana with sodium dodecylbenzenesulfonate, add it into a grinder and grind it into powder; then put it into the mixer, add turpentine, and stir for 10 minutes; then add ethylene glycol to the mixer, and stir for 10 minutes Separate the seeds; finally add ferric oxide and deltamethrin into the mixer, stir for 10 minutes to seed, discharge, and filter through a 120-mesh gauze. The operation process is carried out at room temperature.

[0034] According to the measurement of Guangzhou Institute of Chemical Technology, Chinese Academy of Sciences, the main parameters are ...

Embodiment 2

[0044] Same as embodiment one. Among them, 120 kg of pure spore powder of Beauveria bassiana; 20 kg of sodium dodecylbenzene sulfonate; 300 kg of turpentine; 1600 kg of ethylene glycol; 2 kg of ferric oxide; 1 kg of deltamethrin.

Embodiment 3

[0046] Same as embodiment one. Among them, 115 kg of pure spore powder of Beauveria bassiana; 60 kg of sodium dodecylbenzene sulfonate; 200 kg of turpentine; 1700 kg of ethylene glycol; 1.1 kg of ferric oxide; 3 kg of deltamethrin.

[0047] The Beauveria bassiana suspension of the present invention does not need to be diluted during use, and can be directly used for spraying.

Abstract

A muscardine suspension suitable for ultra-low-capacity spray by airplane is prepared from muscardine spore powder, sulfonate as anionic emulsifier, turpentine, polyol, UV shielding agent, and chemical insecticide. It has high flash point and flowability, low volatilization and no damage to host plant.

Description

technical field [0001] The invention relates to a biological pesticide, in particular to a Beauveria bassiana suspending agent for ultra-low volume spraying. technical background [0002] Beauveria bassiana is an important entomopathogenic microorganism, which has been used as a fungal insecticide since the beginning of last century. Since the 1950s, my country has begun to artificially cultivate Beauveria bassiana to control pests, and has achieved good control effects. In recent decades, Beauveria bassiana has been the preferred microbial insecticide for pest control in forestry. From leaf-eating pests such as pine caterpillars to borer pests such as longhorns, and underground pests such as grubs, all can be isolated to the corresponding Bacteria strains are artificially expanded and cultivated to make Beauveria bassiana insecticide. [0003] In the past, the dosage form of Beauveria bassiana was mainly powder, and the compost and the mycelia and spores of Beauveria bass...
