Description

A kind of pumpkin plant protection agent and preparation method thereof
Technical field
The invention belongs to agricultural technology fields, and in particular, to a kind of pumpkin leaf portion fungal disease prevention and treatment plant protection agent and its Preparation method.
Background technique
Pumpkin is a kind of public vegetable crop being fond of, and has a very high edible and medical value, but cultivation from The fungal diseases such as powdery mildew, anthracnose, epidemic disease, downy mildew often occur to Adult plant for seedling stage, prevent at present these diseases It controls mainly using chemical prevention method, such as triadimefon, carbendazim, Bravo, Mancozeb, although these medicaments belong to low toxicity low Remains of pesticide, but there is timeliness, need interval just to spray within 5-7 days using primary, medicament spray in pumpkin plant pathogenic process It spills number up to 3-5 times, control cost is high, and there are certain harm to people and animals and environment.
Summary of the invention
In order to solve deficiency in the prior art, the purpose of the present invention is to provide a kind of pumpkin plant protection agents, and further The method for preparing the plant protection agent is provided.The plant protection agent can form natural fungi-proofing sterilization barrier together in pumpkin blade surface, Effectively inhibit dip dyeing of the pumpkin fungal pathogen disease to plant, entire growth course only needs spray 1-3 times, substantially reduces pesticide dosage It applies, reduces pesticide environmental pollution.
To achieve the goals above, the present invention use the specific scheme is that
A kind of pumpkin plant protection agent, it includes component and its quality volume fraction be respectively as follows: the poly- alkyl of siloxanes of 0.05-0.2% Oxide block copolymer, the nano silica of 0.01-1%, the chitosan of 0.8-1.0% and 0.01-0.1% N- (2- benzo miaow Oxazolyl) methyl carbamate.
As the further optimization to above scheme, the component and its quality volume fraction that the plant protection agent includes are distinguished Are as follows: 0.1% siloxanes poly- trialkylphosphine oxide copolymer, 0.05% nano silica, 0.9% chitosan and 0.05% N- (2- benzimidazolyl) methyl carbamate.
The present invention further provides the methods for preparing above-mentioned pumpkin plant protection agent, comprising the following steps:
Step 1: weighing chitosan and N- (2- benzimidazolyl) methyl carbamate, dissolved respectively with acetic acid, it is poly- to obtain shell Sugar juice and N- (2- benzimidazolyl) methyl carbamate solution;
Step 2: weighing nano silica and the poly- trialkylphosphine oxide copolymer of siloxanes;Weighed nano silica is added Enter into ethylene glycol simultaneously stirring and dissolving, add the poly- trialkylphosphine oxide copolymer of weighed siloxanes, stirs, obtain suspension;
Step 3: by chitosan solution obtained by suspension obtained by step 2 and step 1 and N- (2- benzimidazolyl) carbamic acid The stirring of distilled water constant volume is added in methyl ester solution mixing, prepares pumpkin leaf portion fungal disease prevention and treatment plant protection agent.
The utility model has the advantages that
Plant protection agent of the present invention includes the poly- trialkylphosphine oxide copolymer of siloxanes, nano silica, chitosan and N- (2- benzene And imidazole radicals) four kinds of components of methyl carbamate, it is preferable to the control efficiency of pumpkin disease, wherein the poly- alkyl oxidation of siloxanes Composition copolymer avoids drug effect from being lost as a kind of emulsifier so that plant protection agent is easier to be attached to blade face cutin layer surface;Nanometer two Silica itself has certain antibacterial effect, can act synergistically with N- (2- benzimidazolyl) methyl carbamate and inhibit disease Evil, chitosan are primarily used to form overlay film and are attached to blade face surface layer, formed with other components collective effect in pumpkin leaf surface One of fungi-proofing sterilization barrier, can not only prevent germ from invading, additionally it is possible to play bactericidal effect to germ, reduce fungicide It uses, reduces blade face residual, reduce cost, reduce environmental hazard, be conducive to protect environment.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described.
Embodiment 1
A kind of pumpkin plant protection agent, it includes component and its quality volume fraction be respectively as follows: siloxanes poly- trialkylphosphine oxide copolymerization Object 0.05%, 0.01%, 0.8% chitosan of nano silica and 0.01% N- (2- benzimidazolyl) methyl carbamate.
The preparation method of above-mentioned plant protection agent, concrete operations are as follows:
(1) N- (2- benzimidazolyl) methyl carbamate is weighed according to above-mentioned quality volume fraction, is carried out with a small amount of acetic acid molten Solution, is configured to N- (2- benzimidazolyl) methyl carbamate solution;
(2) chitosan is weighed according to above-mentioned quality volume fraction, with a small amount of acetate dissolution, is configured to chitosan solution.
(3) nano silica and the poly- trialkylphosphine oxide copolymer of siloxanes are weighed according to above-mentioned quality volume fraction, it is first First nano silica is added in a small amount of ethylene glycol and is stirred, adds the poly- trialkylphosphine oxide copolymer of siloxanes, is stirred, It is configured to suspension.
(4) chitosan of N- (2- benzimidazolyl) methyl carbamate solution, step 2 preparation for step 1 being prepared The suspension that solution and step 3 are prepared is mixed, that is, prepares pumpkin leaf portion fungal disease plant protection agent.
Embodiment 2
A kind of pumpkin plant protection agent, it includes component and its quality volume fraction be respectively as follows: siloxanes poly- trialkylphosphine oxide copolymerization Object 0.2%, 1%, 1.0% chitosan of nano silica and 0.1% N- (2- benzimidazolyl) methyl carbamate.
Preparation method is same as Example 1.
Embodiment 3
A kind of pumpkin plant protection agent, it includes component and its quality volume fraction be respectively as follows: 0.1% siloxanes poly- alkyl oxidation Composition copolymer, 0.05% nano silica, 0.9% chitosan and 0.05% N- (2- benzimidazolyl) carbamic acid first Ester.
Preparation method is same as Example 1.
In order to further prove the disease-controlling effect of plant protection agent of the present invention, following tests is done: only to spray clear water (CK1) and only it sprays 0.05%N- (2- benzimidazolyl) methyl carbamate (CK2) and does control group, benefit is prepared with embodiment 3 Pumpkin leaf portion fungal disease is prevented and treated plant protection agent and is carried out once when pumpkin is colonized 90 days as experimental group, control group and experimental group Foliar spray.In pumpkin harvesting, to leaf portion fungal disease, the survey showed that: the powdery mildew of experimental group, anthracnose, epidemic disease, The disease index of downy mildew is respectively 0%, 3%, 1% and 0%, and the disease index of control group CK1 is respectively 0%, 16%, 14% and 0%, The disease index of control group CK2 is respectively 0%, 7%, 5% and 0%, and the blade of experimental group holds the green phase and relatively compares group leader.Therefore, Plant protection agent of the present invention has preferably disease-controlling effect compared to the independent fungicide that sprays.
Similarly, it using embodiment 1 and the plant protection agent of the preparation of embodiment 2 as experimental group, shows more preferable than control group Ground bactericidal effect and longer hold the green phase.
It should be noted that embodiment described above is interpreted as illustrative, to be not intended to limit the present invention protection Range, protection scope of the present invention are subject to claims.To those skilled in the art, without departing substantially from of the invention real Under the premise of matter and range, some nonessential modifications and adaptations made to the present invention still fall within protection scope of the present invention.
