Description
Technical field
The present invention relates to pesticide, be specifically related to a kind of non-harmful pesticide and preparation method thereof, belong to technical field of pesticide.
Technical background
The disease of crops causes crops quality to reduce such as preventing and treating not in time, and yield declines, and severe patient even has no harvest, and gives
Agricultural production brings huge loss.Pesticide is one of means of production important during proportion of crop planting.Increasing yield, subtracting
The generation of few disease, pesticide all plays a very important role.But many pesticide are again to have material, bring in producing and using
Environmental pollution and Pesticide Residue.During proportion of crop planting, a large amount of uses of pesticide, cause that agriculture is residual to exceed standard, in food
Poison event frequently occurs, thus the non-environmental pollution control of corps diseases more can meet the demand of the ecological agriculture, for most having development latent
The disease control means of power.
Summary of the invention
The technical problem to be solved is to provide a kind of non-harmful pesticide and preparation method thereof.
The technical problem to be solved realizes by the following technical solutions:
A kind of non-harmful pesticide, it is characterised in that include the raw material composition of following deal: modified coal ash 15-30 part, change
Property starch 10-20 part, Gypsum Fibrosum 10-30 part, Calx 3-8 part, make Emulsion.
Each raw material be preferably: modified coal ash 20 parts, modified starch 5 parts, gypsum powder 20 parts, Calx 5 parts, make
Emulsion.
Its preparation method of described modified coal ash is: put into by flyash in container, add 1 times 10% grass
Aqueous acid, stirs, and places more than 60 minutes, dry, pulverize.Fine coal ashes is to receive the flue gas after coal combustion
Catch the fine ash got off, be the primary solids refuse of coal-burning power plant's discharge.
Described modified starch is made up of the raw material of following component: starch 50 parts, sodium hexameta phosphate 1 part, 40 parts of water, phosphoric acid
2 parts, sodium hydroxide 5 parts, Borax 1 part, bentonite 20 parts.Its preparation method is: starch, sodium hexameta phosphate are put into appearance
In device, stirring mixing, add 20 parts of water, stir 5 minutes, stand 30 minutes, add 10 parts of phosphoric acid, water, stir,
Stand 30 minutes, add sodium hydroxide, Borax, bentonite and 10 parts of remaining water, stir, dry, pulverize.
Described Calx preparation method is that quick lime adds water ripening, dry, pulverize.
It is a further object of the present invention to provide the preparation method of the preparation non-harmful pesticide of the present invention, it is characterised in that: take
Modified coal ash, Gypsum Fibrosum add the water of 10 times amount, are heated to boiling 1 hour, filter, and take filtrate, add modified starch, ripe stone
Ash, fully dispersed makes Emulsion.
So far the present invention is completed, the non-harmful pesticide of one that the present invention provides, downy mildew, the grey mold to crops
The Common Diseases such as disease, powdery mildew have preferable prevention effect；The present invention does not contains toxic component, is used for preventing and treating corps diseases high
Effect, nontoxic, environmental protection, safety, low cost.
Further illustrating the present invention below by test example, the purpose of specific embodiment is to further illustrate having of the present invention
Benefit effect, rather than limitation of the present invention.
One, the downy mildew of Fructus Cucumidis sativi is treated
Test method: selecting cucumber variety, sowing time identical, growing way and fertilizer and water condition are basically identical, Fructus Cucumidis sativi their early stage
With 1 field, if 2 process, often process 4 times and repeat, random alignment, plot area 12 m2, Emulsion the most of the present invention processes: at Huang
Melon downy mildew their early stage, every mu adds water 15 kilograms with Emulsion 30 milliliters, in the 1st dispenser of Fructus Cucumidis sativi their early stage, after 7d the 2nd time
Dispenser.Dispenser uses aerosol apparatus even spraying every time, makes to be fully contacted medicinal liquid on cucumber leaves positive and negative；2. clear water processes: take
Water uses aerosol apparatus even spraying, makes to be fully contacted clear water on cucumber leaves positive and negative.
Field efficacy: 7 d carry out Disease investigation respectively before dispenser, after 1 dispenser and after 2 dispensers.Every 5, community takes
Sample, every 2 strains, investigate whole blades by 9 grades of grade scales, record incidence, calculate disease index and prevention effect.Classification
Standard: 0 grade: without scab；1 grade: lesion area accounts for less than the 5% of whole leaf area；3 grades: lesion area accounts for whole leaf area
6%-10%；5 grades: lesion area accounts for the 11%-25% of whole leaf area；7 grades: lesion area accounts for the 26%-50% of whole leaf area；9
Level: sick class area accounts for more than the 50% of whole leaf area.
Drug effect computational methods:
Disease index=∑ (numbers of blade at different levels × state of an illness rank) ÷ (9 × investigation total leaf number)
Prevention effect=(the sick exponential growth rate-process disease of comparison refers to rate of increase) ÷ clear water disease exponential growth rate × 100%.
Result shows, Emulsion of the present invention has preferable preventive effect to cucumber downy mildew, and after 1 medication, 7 d preventive effects are
66.28%, after 2 medications, 7 d preventive effects are 86.35%.
Two, the gray mold of Fructus Lycopersici esculenti is treated
Test method: selecting tomato variety, sowing time identical, growing way and fertilizer and water condition are basically identical, same 1 field in the best fruiting period
Block, if 2 process, often processes 4 times and repeats, random alignment, plot area 15m2, before dispenser, investigate disease index, process 1.
Emulsion of the present invention processes: adding water 60 kilograms (600 times) with Emulsion 100 milliliters, spray pesticide 1 time, after 7d, the 2nd spraying is executed
Medicine, makes Fructus Lycopersici esculenti Herb be fully contacted medicinal liquid；Process 2. clear water to process: take clear water spraying with processing the most identical time, make kind
Eggplant Herb is fully contacted clear water.
Field efficacy: after the 2nd dispenser, 7 d carry out Disease investigation.Taking 5 point samplings, every 5 strains, by 9 grades of classification marks
The whole blades of quasi-investigation, record incidence, calculate disease index and prevention effect.
Calculating drug effect: result shows, Emulsion of the present invention has preferable preventive effect to graw mold of tomato, after the 2nd dispenser, 7 d prevent
Efficiency is 91.7%.
Two, the powdery mildew of Citrullus vulgaris is treated
Same 1 field that test method: select variety of watermelon, sowing time identical, growing way and fertilizer and water condition are basically identical, if 2
Process, often process 4 times and repeat, random alignment, plot area 15m2, before dispenser, investigate powdery mildew disease index, process 1. originally
Invention Emulsion processes: add water 60 kilograms (600 times) with Emulsion of the present invention 100 milliliters, spray pesticide 1 time, the 2nd spraying after 7d
Dispenser, makes Citrullus vulgaris Herb be fully contacted medicinal liquid；Process 2. clear water to process: take clear water spraying with processing the most identical time, make west
Melon Herb is fully contacted clear water.
Field efficacy: after the 2nd dispenser, 7 d carry out Disease investigation.Taking 5 point samplings, every 5 strains, by 9 grades of classification marks
The whole blades of quasi-investigation, record incidence, calculate disease index and prevention effect.
Calculating drug effect: result shows, Emulsion of the present invention has preferable preventive effect to Citrullus vulgaris powdery mildew, after the 2nd dispenser, 7 d prevent
Efficiency is 100%.
The present invention is further illustrated below by detailed description of the invention.
