Problems solved by technology

However, most of the biopesticides are currently used in the form of spraying, and the amount of use is large, otherwise the effect will not be obvious, thus causing pollution to the environment
In addition, the current biopesticides are mainly contact killing, and cannot prevent the pests before they occur.

Embodiment 1

[0012] Mix 25kg of neem seeds, 20kg of lemon eucalyptus branches and leaves, 5kg of croton fruit, 10kg of star anise, 5kg of fennel, 30kg of tea seed cake and 5kg of rapeseed cake, mix and pulverize them into 1-4mm particles, then add 400kg of water to mix, boil for 4 hours, filter out The residue was concentrated to 200kg (40%), then compounded with 3.0kg of OP-10 emulsifier, homogenized, and cooled to obtain a biopesticide.

[0013] Apply the above-mentioned biopesticides on the litchi trunks. The number of experiments is 100. There are an average of 253 insect populations on the original trees. The pesticide was applied throughout the whole process of the end of a fruit period. There were 25 remaining insect populations, and the insect population reduction rate was 90%. The color is dark green, with oily luster, the fruit pedicle is fat and strong, the flowering period is 3 days earlier, the stamens are enlarged, the branch pressing time is long, the fruit is set evenly, th...

Embodiment 2

[0015] Mix 35kg of neem seeds, 10kg of lemon eucalyptus branches and leaves, 15kg of croton fruit, 5kg of star anise, 10kg of fennel, 20kg of tea seed cake and 5kg of rapeseed cake, mix and pulverize them into 1-4mm particles, then add 300kg of water to mix, boil for 3 hours, filter out The residue was concentrated to 176kg (44%), then compounded with 1.76kg of OP-10 emulsifier, homogenized, and cooled to obtain a biopesticide.

[0016] Apply biological pesticides on the trunks of persimmon trees after the small fruit stage. The number of experiments is 200. The width of the application is 10cm, and the thickness of the application is 1mm. The application is once a month. Check after 7 days of application. There is no new insect population, and the bird predation has increased. , the leaf surface turns green, it is oily and shiny, there are no diseased branches, and the fruit drop rate is reduced by 80%. Check after 15 days and there is no abnormal fruit drop. The fruit set is...

Embodiment 3

[0018] Mix and grind 45kg of neem seeds, 10kg of croton fruit, 5kg of fennel, 30kg of tea seed cake and 10kg of rapeseed cake into 1-4mm particles, then add 250kg of water to mix, boil for 3 hours, filter to remove residue, concentrate to 161kg (46% ), then compounded with OP-10 emulsifier 0.805kg, homogenized, and cooled to obtain biological pesticides.

[0019] Apply biopesticides on the citrus trunks. The number of experiments is 300. The width of the application is 8cm, and the thickness of the application is 1mm. The application is once a month, from the end of the previous fruiting period to the end of the next fruiting period. Apply pesticides to prevent and control mites, and the effect of red spiders is 92%. There are no other new insect populations. The leaves are greener, the oil is shiny, the new branches are thick, the petals are thick, the small fruits are increased, the fruits are even, and the hanging time of mature fruits is delayed by one. In July, the fruit ...

Abstract

The invention relates to an environmentally-friendly phytochemical pasty biopesticide and a preparation method thereof. The biopesticide is characterized by being prepared by grinding and boiling the following raw materials in percentage by mass in water: chinaberry seeds 25-45, eucalyptus citriodora branches and leaves 0-20, croton fruit 5-15, star anise 0-10, fennel 5-10, tea seed cake 20-30 and colza cake 5-10, wherein the total mass percentage of the raw material components is 100 percent. The biopesticide is suitable for preventing and controlling pest and disease damages to woody fruit trees of longan, lichee, mango, mandarine, persimmon, apple, snow pear, pomelo and the like and is applied on tree trunks to repel and contact and kill pests. And the biopesticide can obviously improve the photosynthesis of the leaf surfaces, promote the sound growth of the fruit trees, increase the strength of flower stalks and the thickness of petals when applied before blossom, improve fruit setting rates when applied in young fruit period, make fruit avoid drop, ripe fruits even, ripe period advanced or hanging period prolonged when applied in middle fruit period, and lay a basis for shooting promotion and high yield in the coming year when applied after harvest.

Description

technical field [0001] The invention relates to a biological pesticide, in particular to an environment-friendly phytochemical paste biological pesticide and a preparation method of the pesticide. Background technique [0002] The pesticides used to prevent and control fruit tree diseases and insect pests in my country are mainly chemical pesticides, which are sprayed in large quantities during use. Long-term spraying of chemical pesticides will cause serious pollution of air and water and soil resources, and damage the natural ecological chain. Human life safety constitutes a hazard. [0003] At present, there are some studies on biopesticides, among which Chinese patent CN1623401 provides a biopesticide obtained by mixing ephedra, ginger, geranium, leaking reed, angelica dahurica, schisandra, etc., to kill vegetable pests and diseases by contact killing; Chinese patent CN1178636 provides a kind of biopesticide obtained by mixing Aconitum aconitum, castor plant, deer vine, ...
