Description
Technical field
This disclosure relates to agriculture field, and in particular, to a kind of composition pesticide and its application.
Background technique
The problem of mixing of different type disease occurs, rice blast, bacterial stripe are usually present in agricultural production practice
Disease, bacterial angular leaf spot are the diseases for often existing simultaneously or depositing in succession in rice.
Cause the biological factor of plant disease to be known as pathogen, mainly there is fungi, bacterium, virus and viroid etc..Fungi
It is most important pathogenic species group, in the real process of agricultural production, many important disease such as rice blast are by true
It is microbial.Bacterial disease is a kind of disease due to caused by bacterial invasion plant, and bacterial disease recent years occurs non-
Often universal, many important diseases such as bacterial stripe, bacterial angular leaf spot etc. are all as caused by bacterium.
Currently, applying pesticides are controlling plant diseases the most effective means, but existing Pesticidal products can only be to list
The plant disease of one type is prevented and treated, and different types of disease is generally required different pesticide species progress is respectively adopted
Prevention and treatment.Such as: rice blast is generally prevented and treated with Fluoxastrobin or Prochloraz；Bacterial stripe generally use chlorobromide isocyanuric acid or
Zinc thiazole is prevented and treated；Bacterial angular leaf spot is generally prevented and treated with zinc thiazole, kasugarnycin or tiger glue adipic acid copper.
Current disease control pesticide utilization rate is low, and control efficiency is poor, and the prevention and treatment period is long, at high cost, also will cause
Serious environmental pollution.Therefore, need to develop that one kind can carry out integrated control for plurality of plant diseases and control efficiency is prominent
Pesticidal products out.

Testing example 1
Subjects: rice blast fungus
Test method: referring to " People's Republic of China (PRC) agricultural industry criteria NY/T1156.8-2007 ", pot-culture method.It chooses
It is spare to grow consistent 1 heart stage of 3 leaf rice seedlings.Rice blast fungus is cultivated on appropriate media, after spore to be generated, is used
Spore under sterile washing, filtering, is made 1*105The suspension of a spore/ml, it is spare.Preparation is directly diluted with water.
Medical fluid is diluted 300 times and is uniformly sprayed on liquid level to whole wettings, it is spare after medical fluid natural air drying.Every processing 1
Basin, 4 repetitions, and blank control is done in the processing for setting clear water.With spore suspension 3ml spray inoculation, connect for 24 hours before chemicals treatment
Kind, inoculation moves back into humidistat (95% or more relative humidity keeps liquid level to have moisture condensation, 25 DEG C -26 DEG C of temperature) dark condition
Lower moisturizing culture is for 24 hours.Then 25 DEG C -26 DEG C, 12h alternation of light and darkness (intensity of illumination 20000lx), relative humidity 85%-90% again
Under conditions of cultivate 7d.
Investigation: when blank control diseased plant rate reaches 50% or more, the incidence of whole strain blade, classification side are investigated in classification
Method are as follows:
0 grade: whole strain is disease-free；
1 grade: brown scab occur；
3 grades: typical spindle scab occur, lesion area accounts for 5% or less whole leaf area；
5 grades: typical scab, lesion area account for the 6%~25% of whole leaf area；
7 grades: typical scab, sick class's area account for the 26%~50% of whole leaf area；
9 grades: typical scab, lesion area account for 50% or more of whole leaf area.
According to survey data, the disease index and control efficiency of each processing are calculated.
Rice blast fungus control efficiency is as shown in table 1.

On in power, uniformity, water retention property is good, and irrigation and drainage are convenient, and field is without weeds.Rice varieties are Jinyou 458.Application is using benefit
The hand compression sprayer even spraying of agriculture HD-400 type is 600kg/hm according to the application amount of being watered2, per hectare is applied active in medicine
Ingredient 10g, the sample of embodiment 1-20 and comparative example 1-4 are uniformly sprayed respectively each growing area rice plant blade just
On anti-two sides, blank control group is sprayed using rice plant of the clear water to growing area.
Investigation method: 15d investigates the anti-of rice blast, bacillary stripe disease and bacterial angular leaf spot before medicine and after medicine
Control effect.5 points of every cell diagonal line samplings, every investigation are connected 5 clumps, amount to 25 clumps, record total strain number, diseased plant number and sick grade
Number.Control efficiency is calculated by formula (I) and formula (II).Rice disease control efficiency is as shown in table 2.
