Abstract
The invention discloses a kind of rice seedling blight protective agents compound formulations and preparation method thereof, the preparation method includes the following steps: S1, weighs each 50 grams of Chinese prickly ash, chilli, tealeaves, is wrapped in double gauze after mixing, is placed in small fire in 1L water and simmers 120 minutes, filtering, obtains filtrate；S2, resulting filtrate is cooled to room temperature, is separately added into the fludioxonil suspending agent of the 2.5% of 7.5ml and the 2-cyano-3-amino-3-phenylancryic acetate suspoemulsion of 15ml25%, adds water to be settled to 1L, stir and evenly mix, obtain finished product.The present invention is by being added Chinese medicine sterilizing medicament, the very good solution resistance problems of single sterilization mechanism pathogen.
Description
Technical field
The present invention relates to agriculture fields, and in particular to a kind of rice seedling blight protective agents compound formulation and its preparation side
Method.
Background technique
Rice seedling blight is one of Major Diseases of rice seedling, and is occurred when northern area seedling cultivation of rice universal.In water
Damping-off most easily occurs for 1 leaf of rice, 1 heart stage of 1 heart stage to 2 leaf.Rice seedling blight category soil-borne disease, by a variety of fungi mixture infection institutes
It causes.Mainly as caused by the weak property bacterial parasite such as Fusariumsp, Rhizoctonia solani Kuhn.Cause the cause of disease Fusariumsp of rice seedling blight, stand it is withered
Rhizoctonia is generally existing in the soil, and the quantity of these bacterium and the occurrence degree of damping-off are positively correlated, but undesirable environment item
Influence of the part to damping-off is particularly important, such as low temperature, damage to plants caused by sudden drop in temperature and pH value environmental factor be damping-off occur necessary condition,
Rice seedling root is damaged, weak pathogenic is caused to invade, when to often result in rice shoot withered in flakes.Control measure includes:
Selected excellent kind, reasonable vernalization, first frost and Fungicide Mixture are dressed seed；Seedbed is single using hymexazol, metalaxyl and thiram etc.
Agent or mixture carry out spray disinfectant；1 heart stage of 1 leaf of rice shoot, sprays the single doses such as hymexazol, metalaxyl and thiram or mixture；It sprays simultaneously
Root-inducing powder and foliar fertilizer are applied to promote to grow, improves degeneration-resistant disease resistance.Currently, since the long-time service of the single pesticide of tradition makes disease
The drug resistance of opportunistic pathogen is more and more stronger, reduces control efficiency, so that peasant be forced to increase dosage, causes crops pesticide residual
It stays and increases year by year, endanger safety of human and livestock.
Summary of the invention
To solve the above problems, the present invention provides a kind of rice seedling blight protective agents compound formulation and its preparation sides
Method, the very good solution resistance problems of single sterilization mechanism pathogen.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of preparation method of rice seedling blight protective agents compound formulation, includes the following steps:
S1, each 50 grams of Chinese prickly ash, chilli, tealeaves are weighed, is wrapped in double gauze after mixing, it is slow to be placed in small fire in 1L water
It boils 120 minutes, filters, obtain filtrate；
S2, resulting filtrate is cooled to room temperature, is separately added into the fludioxonil suspending agent and 15ml of the 2.5% of 7.5ml
25% 2-cyano-3-amino-3-phenylancryic acetate suspoemulsion, adds water to be settled to 1L, stirs and evenly mixs, obtain finished product.
The present invention is asked by the way that Chinese medicine sterilizing medicament, the drug resistance of the single sterilization mechanism pathogen of very good solution is added
Topic.
Specific embodiment
In order to which objects and advantages of the present invention are more clearly understood, the present invention is carried out below in conjunction with example further detailed
It describes in detail bright.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not intended to limit the present invention.
The embodiment of the invention provides a kind of preparation methods of rice seedling blight protective agents compound formulation, including walk as follows
It is rapid:
S1, each 50 grams of Chinese prickly ash, chilli, tealeaves are weighed, is wrapped in double gauze after mixing, it is slow to be placed in small fire in 1L water
It boils 120 minutes, filters, obtain filtrate；
S2, resulting filtrate is cooled to room temperature, is separately added into the fludioxonil suspending agent and 15ml of the 2.5% of 7.5ml
25% 2-cyano-3-amino-3-phenylancryic acetate suspoemulsion, adds water to be settled to 1L, stirs and evenly mixs, obtain finished product.
In order to preferably verify practical application effect of the invention, illustrated below with example.
Reagent agent: (1) test medicine: 1L/m after 22.5 times of finished product medicament dilutions2, poured.(2) comparison medicament:
99% hymexazol pulvis and 40% first frost thiram wettable powder.(3) controlling object: rice seedling blight.
Method: using the Nutrition Soil of sterilizing as matrix, greenhouse disk nursery, every disk sows 90g seed, and every processing is repeated 3 times.It is vertical
Withered silk kernel fungus inoculation uses bacterium local method: the Rhizoctonia Disease for cultivating 14d and sickle-like bacteria are inoculated in sorghum grain culture medium respectively
On, it is uniformly mixed, is sub-packed in seedlings nursing plate, then by rice paddy seed with the Nutrition Soil of sterilizing respectively by 2% bacterium amount that connects after 1 week
It is seeded in seedlings nursing plate respectively, sets in 25-28 DEG C of greenhouse of temperature and cultivate.One leaf wholeheartedly when carry out medicament spray, two leaves wholeheartedly when
The pouring of noon cold water hurts root and promotes morbidity, and 20d investigates the disease incidence of each disk rice plant, statistics prevention and treatment effect after each processing emergence
Fruit.
Disease incidence (%)=morbidity seedling number/investigation sum × 100
Control efficiency (%)=(control disease incidence-processing disease incidence)/control disease incidence × 100
Processing:
Processing 1: one composite drug of example
Processing 2: hymexazol
Processing 3: first frost thiram
CK: clear water control
The control efficiency of 1 rice seedling blight of table
As seen from the data in Table 1, hymexazol, first frost thiram found rice with the compound formulation configured according to example one withered
There are apparent differences with preventive effect for the disease incidence of disease, and the control efficiency of compound formulation is significant, better than the control efficiency of comparison medicament,
In the case where single medicament develops drug resistance, which has broad application prospects.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
