Description
Technical field
The present invention relates to agricultural disease prevention and control field, specifically a kind of sterilization group containing benziothiazolinone and fluorine thiazole pyrrole ethyl ketone sodium
Compound and its application.
Background technology
Benziothiazolinone (Benziothiazolinone) is the heterocyclic of Shaanxi Xida Huate Science ＆ Technology Industrial Co., Ltd.'s exploitation
Bactericide.Molecular formula：C7H5NOS, chemical name：1,2 benzisothiazole-3-ketone.
Benziothiazolinone is a kind of efficient, low toxicity, and broad-spectrum germicide, can destroy pathogen cell membrane protein and synthesis is
System, so as to suppress pathogen breeding, pathogen cell metabolism is disturbed, makes its physiologic derangement, cause pathogen dead.The change
Compound has good prevention effect to bacterium, fungus-caused multiple kinds of crops disease, and fool proof to crops and environment.
Fluorine thiazole pyrrole ethyl ketone (oxathiapiprolin), chemical name 1- (4- { 4- [(5R S) -5- (2,6- difluorobenzenes
Base) -4,5- dihydro -1,2- oxazole -3- bases] -1,3- thiazol-2-yls } -1- piperidyls) -2- [5- methyl -3- (trifluoromethyl) -
1H- pyrazol-1-yls] ethyl ketone, the first piperidyl thiazole isoxazoline series bactericidal agent newly researched and developed for E.I.Du Pont Company.Fluorine thiazole pyrrole second
Ketone has unique action site to Oomycete pathogen, and mechanism of action is suppresses oxygen steroid binding proteins (OSBP), to Ma Ling
Potato, grape, vegetables and other Featured crops diseases have remarkable preventive effect.But fluorine thiazole pyrrole ethyl ketone action site is single, kills
Microbial inoculum resistance Action Committee (FRAC) thinks that it has middle high-level resistance risk, it is necessary to carry out resistance management.
Downy mildew is the plant disease as caused by the downy mildew in fungi.Downy mildew is obligate parasite, and downy mildew is general
First fallen ill since lower blade, early stage produces the water stain shape dot of light green, scab edge unobvious, and Later development is Huang
The irregular scab of color, blade back produces canescence mould layer during high humidity, gradually becomes Dark grey.Downy mildew is with egg spore in soil
In, survive the winter (such as downy mildew of millet) on invalid body or seed, or hidden with mycelium in stem, bud (such as downy mildew of garpe) or seed
Inside survive the winter (such as Chinese cabbage downy mildew), turn into the primary source of infection of next year disease, Growing season is infected again by sporangium.
Cucumber downy mildew, " horse race is dry ", " dry leaves " are commonly called as, seedling stage strain all can be aggrieved, mainly cause harm blade and stem, volume
Palpus and bennet are aggrieved less.Downy mildew is that the most universal, disease for the most serious that causes harm occurs in cucumber cultivation.Its state of an illness oncoming force is violent,
Morbidity weight, propagate soon, such as prevent and treat not in time, destructive loss will be caused to cucumber.
Downy mildew of garpe is a kind of global grape disease.Each viny region in China is distributed, especially in rainy tide
Humid Area occurs generally, is one of grape Major Diseases.Found in U.S.'s amur grape within 1834.China's notebook in 1899
The generation of disease.When falling ill serious, blade is shrivelled caducous, young sprout undergrowth, and fruit yield reduces, quality deteriorates, plant cold-resistant
Property is poor.
Each producing region in the widely distributed world of downy mildew.Nineteen twenty-one is found in the Northeast of China first, with northeast and
North China generation is more universal, and the nice and cool area morbidity of soybean growth period weather is heavier.But causing harm property of majority is little, and morning is caused when serious
Phase fallen leaves, blade are withered, kind grain goes rotten, and the underproduction is up to 30%~50%.Seedling, strain blade, pod and beans can be killed, and be carried disease germs
The seedling that seed is grown, can system morbidity.
As potato planting area gradually expands, continuous cropping problem is more universal, in potato seed growing area tar spot increasingly
Seriously, and morbidity is more universal, can typically cause the potato underproduction 15% or so, indivedual times destroy up to full field, serious shadow
The yield and quality of potato is rung.Its pathogenic bacteria can also infect pea in addition to potato is infected.
Above-mentioned four kinds of insect pests are the diseases that agricultural production is difficult to prevent and treat, and fluorine thiazole pyrrole ethyl ketone has certain preventing and treating effect to it
Fruit, but action site is single, easily produces resistance, causes prevention effect undesirable.

Single dose and each Mixed Pharmacy set 5 various concentrations gradients (different according to proportioning on the basis of pilot study result, concentration ladder
Degree setting is also different, and bacteriostasis rate is set in the range of 5%-90% by geometric progression).If clear water control group, three are repeated
It is secondary.Using mycelial growth rate method, by cultured pathogen, aseptically with diameter 5mm card punch, from colony edge
Bacteria cake is cut, bacteria cake is connected to the culture medium flat plate center of different agents concentration with transfer needle, mycelia is face-up, covers ware lid,
It is placed in the baking oven of preference temperature and cultivates；When control group bacterium colony covers with, with kind of calliper colony diameter, unit is millimeter
(mm).Each bacterium colony is each once with crossing method vertical survey diameter, takes its average value.Each medicament is calculated according to measurement result
The mycelial growth inhibition rate of processing, recurrence point is done according to each drug concentration logarithm value and corresponding mycelial growth inhibition rate niqueMin
Analysis, obtain the EC of each medicament50, according to the toxicity index level co-toxicity coefficient (CTC) of the abundant method calculating medicaments of Sun Yun.
Survey toxicity index (ATI)=(standard agent EC50/ for reagent effect EC50)×100
The toxicity index of A percentage composition+B medicaments in toxicity index × mixture of theoretical virulence coefficient (TTI)=A medicaments
B percentage composition in × mixture.
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100.
Work as CTC<When 80, composition shows as antagonism；When 80<CTC<When 120, composition shows as summation action；
Work as CTC>When 120, composition shows as synergistic effect.
The benziothiazolinone of table 1 is compounded to cucumber downy mildew Toxicity Determination with fluorine thiazole pyrrole ethyl ketone different proportion

Relative control effect (%)=(check plot disease index-treatment region disease index)/check plot disease index × 100%
Experimental result is as follows：
The benziothiazolinone fluorine thiazole pyrrole ethyl ketone complex preparation of table 4 prevents and treats black scurf of potato result of the test
From table 4, it can be seen that benziothiazolinone fluorine thiazole pyrrole ethyl ketone bactericidal composition is black to potato under relatively low dosage
The prevention effect of mole disease is better than comparison medicament prevention effect, shows excellent synergetic.Above-mentioned common medicine can be used as
Upgrading of the agent in preventing and treating black scurf of potato substitutes agricultural chemicals.
