Abstract
An optical agricultural chemical in the form of aqueous solution containing photocatalyst contains TiO2, organosilicon compound, and chlorode and/or sulfate and/or oxide. Its advantages include high safety, no damage to environment, low cost and high effect.
Description
The present invention relates to a kind of agricultural chemicals of controlling plant diseases, particularly relate to a kind of agricultural chemicals and application thereof that contains photochemical catalyst.
At present, photosemiconductor material such as titanium dioxide etc. are causing extensive concern in the application study aspect the environment such as antibiotic, self-cleaning.This photosemiconductor material is under the effect of the ultraviolet light about natural daylight or 360nm, the surface can inspire free electron and form the hole of a positively charged simultaneously, and then cause a series of redox reactions, generation has the hydroxyl and the active oxygen radical of very strong redox ability, decompose the various organic compounds that are adsorbed in the surface, but thereby killing bacteria, microorganisms such as virus.Photochemical catalyst can not have any impact to human body, can not cause any environmental pollution yet, thereby has been applied to various life goods, plays effects such as antibiotic, antifouling, smelly, the air cleaning of disappearing.But have not yet to see the control that report is used it for plant pest.
The objective of the invention is to develop a kind of agricultural chemicals that contains titanium dioxide class photosemiconductor material, play desinsection, effect such as antibiotic, antiviral, and can not produce decomposition the organic substance of plant surface.
Optical agricultural chemical of the present invention is water miscible colloidal solution, mainly contains following three kinds of compositions:
(1) 1～4% titanium dioxide;
(2) a kind of organo-silicon compound, content are 0.5～2 ‰;
(3) one or more chlorides and/or one or more sulphate and/or one or more oxides;
Wherein (3) content of planting composition is 0.5～2%.
Described titanium dioxide preferred content is 1～3%, and optimum content is 2%.
Described organo-silicon compound comprise silane coupler, silicon tetrachloride, ethyl orthosilicate, sodium silicate or silica;
Described chloride comprises zinc chloride, copper chloride, aluminium chloride or silver chlorate etc.;
Described sulphate comprises copper sulphate, aluminum sulfate, zinc sulphate or ferrous sulfate;
Described oxide comprises iron oxide, tungsten oxide, aluminium oxide etc.
The preparation method of optical agricultural chemical of the present invention is:
1. the titanium salt compound water solution is added alkali and prepare titanium hydroxide, described titanium salt compound can be from titanium sulfate, selects in the titanium tetrachloride etc.;
2. the metatitanic acid and the aqueous solution that contains hydrogen peroxide are reacted, make the aqueous solution that contains titanium dioxide;
3. add organo-silicon compound and chloride, sulphate or oxide, and stir, make the optical agricultural chemical storage solution.Using method:
Before using the agricultural chemicals storage solution is added the water of 5～20 times of volumes, be diluted to desired concn.Spray or be applied in leaf, stem, flower, fruit, the root of plant, or soak plant seed, or spray is distributed in soil surface, to disinfecting soil.
Optical agricultural chemical provided by the invention is safe and harmless, meets environmental protection requirement, and preparation technology is easy, with low cost, this optical agricultural chemical is sprayed in plant surface, or soak plant seed, can form clear films after the drying.Under faint natural daylight and artificial light effect, but killing pathogenic bacteria, virus reaches preventing disease theraping effect, and can the organic matter of plant surface not had a negative impact.
Below in conjunction with embodiment the present invention is done further detailed elaboration:

1, control pepper virus disease
10 times of embodiment 1 agricultural chemicals dilute with waters are sprayed their early stage respectively and the capsicum blade of not falling ill, weekly, connect and spray three times.Use running water as blank in addition, spray according to said method.
The result:
Behind the disease plant spraying pesticide, blade necrosis and deformity are slowed down to disappearance, and disease plant does not see neopathy.
Control group disease plant blade produces dense, light alternate piebald or the blade deformity takes place or clump bunch shape.Indivedual neopathy plant also appear in former not disease plant.
2, control tomato gray mold
15 times of embodiment 2 agricultural chemicals dilute with waters are sprayed their early stage respectively and the tomato blade of not falling ill, every six days once, connect and spray three times.Use running water as blank in addition, spray according to said method.
The result:
Behind the disease plant spraying pesticide, dead seedling does not take place, and the cauline leaf putrefactive phenomenon slows down to disappearance, disease plant does not see neopathy.
Control group disease plant cauline leaf rots, there is grey mold on the surface, and has dead seedling to occur.
3, prevention bean anthracnose
Dye the Kidney bean angle seed 20 minutes of bean anthracnose pathogenic bacteria one Deuteromycotina Colletotrichum beans thorns cup fungi with 5 times of immersions of embodiment 3 agricultural chemicals dilute with waters, dry and detected in back 15 minutes, do not detect germ.
4, prevention tomato virus disease
Dye the tomato seed 20 minutes of tobacco mosaic virus with 5 times of immersions of embodiment 4 agricultural chemicals dilute with waters, dry and detected in back 15 minutes, do not detect virus.
5, prevent and treat common bacterial blight of bean
20 times of embodiment 5 agricultural chemicals dilute with waters are sprayed their early stage and not incidence of leaf, stem and fruit pod respectively, every ten days once, connect and spray three times.Use running water as blank in addition, spray according to said method.
The result:
Behind the disease plant spraying pesticide, cauline leaf scab, withered phenomenon are slowed down to disappearance, and disease plant does not see neopathy.
Leaf curling deformity, shrinkage appear in control group, and the stem that partly is injured is bronzing long strip type depression spot, and spot also appears in indivedual fruit pods.
