Abstract
The invention relates to a biological pesticide of microemulsion and granules of agricultural peppermint oil with vegetality and no toxicity and is characterized by good solubility, dispersity, adhesiveness, dilutability, keeping property, slow releasing property and testability of production and use of chemical pesticide. The preparation has better prevention effect to powdery mildew, downy mildew and blight of crops. The invention not only has stronger bacteriolysis effect, but also has better prevention effect, embodies that the microemulsion and granules of agricultural plant pesticide can be produced under industrialization, and provides a novel pesticide with no toxicity and vegetality for agriculture.
Description
Technical field
The invention belongs to botanical pesticide.The peppermint oil that extracts by the cauline leaf of plant Mentha canadaensis L, through processing technology, create can large-area applications the agricultural biological pesticidal preparations.
Background technology
Current poisonous chemical pesticide contaminated environment is harmful to the healthy of the mankind so that chronic poisoning.Being badly in need of nontoxic biological agricultural chemicals replaces or reduces noxious material, cleaning ambient.
The soil pesticide that some local methods are produced, a no standard, the two no methods of inspection, three content effect instabilities do not have the preparation of moulding, can not suitability for industrialized production.
Peppermint oil is as far back as medicine, edible and make up to go up and use, and direct large-area applications in agricultural production.Because of there not being the preparation of agricultural moulding, do not have the problems such as dispersiveness, adhesivity, dilution, instant capacity, slow release, storage, inspectability of pesticidal preparations requirement.
Summary of the invention
This invention can be made the biopesticide of formulations such as nontoxic agriculture peppermint oil microemulsion, granule by production technology.
The preparation of the agricultural menthence that this invention is made has features such as the identical instant capacity of chemical pesticide, dispersiveness, adhesivity, dilution highly, slow release, storage, inspectability.
The agricultural menthence aqueous emulsion of this invention, can prevent and treat the diseases such as powdery mildew Erysiphe herocle.sp downy mildew peronospora parasitica.sp fusarium wilt Fusarium oxysporum.sp of crops, can also repellent cabbage caterpillar Artogeia rapae.sp etc. insect.

(4) proportioning: peppermint oil 10-20%, solvent 40-70%, emulsifier 10-12%, thinner 10-30%.
(5) technological process: the peppermint oil through being up to the standards injects agitator tank, adds methyl alcohol and stirs for the first time 30-60 minutes, and (45-60 rev/mins) add emulsifier more according to quantity and stirred for the second time 30-60 minutes, adds thinner and stirs for the third time 60-70 minutes.Control laboratory check enters conveyer belt after qualified and imports the automatic packaging machine into and pack.
Example 1:
The prescription of 20% agricultural menthence microemulsion, explained hereafter flow process and bacteriolyze effect
Prescription:
Peppermint oil 20%, formaldehyde 55%, op2110%, pure water 15%.
20% agricultural menthence microemulsion, the bottling 100ml/ bottle that will configure by above-mentioned prescription and technological process.
Test plant: cover with on the stem of white powder germ and do bacteriolytic test, the dilution of different multiples is splashed into 1 have on the stem that covers with the white powder germ, can see that then and there the white powder bacterium colony dissolves disappearance immediately.Contrast the diameter and the time length of its bacteriolyze.Clear water is done contrast.See the following form:
| Multiple | Time | The bacteriolyze diameter length | The bacteriolyze effect |
| 1 of former medicine | 2-5 seconds | 6mm | Greatly |
| 100 times 1 | 10-20 seconds | 6mm | Greatly |
| 500 times 1 | 40-60 seconds | 6mm | Greatly |
| 1000 times 1 | 2-5 minutes | 4—5mm | Greatly |
| 5000 times 1 | 10-20 minutes | 3—4mm | Greatly |
| 10000 times 1 | 30 minutes | 0mm | Do not have |
| 1 in clear water | 30 minutes | 0mm | Do not have |
Example 2:
10% agricultural menthence micro-emulsion formulation, production technology and bacteriostasis
Batching: the 60%600kg.op2110%100kg pure water 20%200kg of 10% peppermint oil 100kg, first.(preparing one ton of preparation)
Dropping into crude oil by above-mentioned technology adds auxiliary agent, stirs for three times by example 1 method and make 10% microemulsion.Pack into and make the commodity preparation in the 250ml bottle.
In culture dish, make bacteriostatic test for examination fusarium wilt bacterial classification.3 times reproducible results is as follows, reagent agent 10% agricultural menthence microemulsion.
Dilute 100 times, 500 times, 1000 times, 5000 times, 10000 times respectively by preparation, the contrast medicine is 50% carbendazol wettable powder, is made as 100 times, 500 times, 1000 times, 5000 times, 10000 times respectively, contrasts with clear water.
These soups are used the paper circle of 3mm diameter respectively, invade medicine after, put into the culture dish that connects bacterium, three in every ware.Be placed in 28 ° of constant temperature and cultivated 7-10 days, observe the colony growth situation.The results are shown in following table:
| 10% peppermint oil microemulsion | 100 times | 500 times | 1000 times | 5000 times | 10000 times |
| 10% peppermint oil microemulsion | Aseptic | Aseptic | Aseptic | Antibacterial circle diameter 20mm | Antibacterial circle diameter 12mm |
| But 50% carbendazim wet-milling | 100 times | 500 times | 1000 times | 5000 times | 10000 times |
| But 50% carbendazim wet-milling | Aseptic | Antibacterial circle diameter 21mm | Antibacterial circle diameter 13mm | Antibacterial circle diameter 5mm | Cover with bacterium |
