Description
Technical field
The present invention relates to composite bactericidal composition of a kind of bromothalonil and methoxy acrylic bactericide and application thereof, particularly a kind of with bromothalonil as a kind of bactericidal composition and application thereof in first active component and kresoxim-methyl, Fluoxastrobin, Enestroburin, pyraclostrobin, oxime bacterium ester, the SSF 126 as second active component, and the use of synergetic effect additive bigcatkin willow oxime acid (SHAM) in above composition, belong to the agriculture chemical compounding technical field.
Background technology
Anthracnose (anthracnose) pilosity is born in the warm moist area, infects multiple draft and woody plant, is often to send out one of multiple emphasis disease on vegetables, fruit tree, the forest in recent years.In agricultural production, vegetables, fruit tree anthracnose is mainly by Deuteromycotina (Deuteromycotina) Colletotrichum, coiling long spore belongs to, fungi in the colletotrichum (Colletotrichum) causes, as spore shape thorn dish spore bacterium (Colletotrichumgleosporioides Penz.), melon thorn dish spore (Colletotrichum lagenarium), black line anthrax-bacilus (Col-letotrichumdematium (Pers.) Grove), due to the glue spore thorn dish spore (Colletotrichumgloeosporioides (Penz) Sace), sharp spore anthrax-bacilus (ColletotrichumacutatumSim-monds).Anthracnose is because of different plants, and its pathogen is different, can cause a large amount of underproduction, fruit-vegetable quality to descend, even total crop failure.Germ survives the winter in residual body of host or soil with mycelium, conidium or aceravlus, and Lao Ye is morbidity at the beginning of 4 months, and 5 develop rapidly between June, and young leaves is then fallen ill since August.How conidium infects from the wound by wind and rain, propagation such as water.Plant overstocked, improper ventilation, leaf intersects easily susceptible mutually.Germ growth thermophilic is 26 ℃ to 28 ℃, and the generation of conidium optimum temperature is 28 ℃ to 30 ℃, and the appropriate pH value is 5 to 6.High humidity, sick portion be moistening, water droplet or moisture film are arranged is that pathogen produces a large amount of conidial essential condition, and cloudy weather for several days running morbidity in season is heavier.Influenced by snow disaster, once caused a large amount of oranges and tangerines gardens such as North Guangdong, west of Guangdong Province Yuexi to ruin the garden in 08 year, cause heavy losses for local orchard worker, and have in the whole nation and to increase the weight of trend year by year, is the especially oranges and tangerines heavy difficult point disease of producing of agricultural production.At present, preventing and treating this sick main flow medicament is Prochloraz, thiophanate-methyl, carbendazim etc., but owing to use for many years, its resistance is quite serious, and using dosage is near this compounds maximum.Simultaneously, the thiophanate-methyl of benzimidazole, carbendazim have higher teratogenesis, carcinogenicity and embryotoxicity, and high dose uses and is unfavorable for health environment-friendly.

2Totally 5 chemicals treatment repeat totally 18 sub-districts (adding blank), 30 square metres of every sub-district areas 3 times.The knapsack hand sprayer spraying is adopted in test, respectively at 7,10,15 days investigation disease indexs before the medicine and behind the medicine and calculate preventive effect.
State of an illness stage division:
0 grade: no scab;
1 grade: lesion area accounts for below 5% of fruit area;
3 grades: lesion area accounts for the 6%-10% of fruit area;
5 grades: lesion area accounts for the 11%-25% of fruit area;
5 grades: lesion area accounts for the 16%-25% of fruit area;
7 grades: lesion area accounts for the 26%-50% of fruit area;
9 grades: lesion area accounts for more than 51% of fruit area.
Result of the test shows: each concentration of treatment of reagent agent formulation embodiment 1 (50% bromothalonil kresoxim-methyl missible oil) all has remarkable preventive effect to watermelon anthrax, 7 days, 10 days 250g a.i./hm behind its Chinese medicine
2With contrast medicament 25% bromothalonil missible oil 800g a.i./hm
2, 30% kresoxim-methyl wetting powder 250g a.i./hm
2Preventive effect is suitable, 15 days and 400g a.i./hm behind the medicine
2, 550g a.i./hm
2The reagent agent preventive effect illustrates that apparently higher than the contrast medicament 50% bromothalonil kresoxim-methyl missible oil control watermelon anthrax not only has good quick-acting, has lasting effect preferably simultaneously, and synergy is remarkable.Test does not see that watermelon and beneficial organism are had harmful effect.
Each processing of table 4 is to the preventive effect of watermelon anthrax
Biological Examples 5 composition for preventing and controlling pepper anthracnose field trials
Subjects is the open country pepper anthracnose, and it is medium experimental field to be chosen in soil fertility, and soil fertility is even, and the cultivation management condition is good, and capsicum grows fine, and anthracnose takes place in the uniform plot.Test medicine and concentration gradient are formulation embodiment 5 (20% bromothalonil pyraclostrobin water) emulsion 280g/hm
2, 320g/hm
2, 360g/hm
2Contrast medicament 25% bromothalonil missible oil 560,640,720g/hm
2Reach 25% pyraclostrobin missible oil 120,150,180g/hm
2Adopt district's group arrangement at random, 1 blank repeats 4 times, amounts to 40 sub-districts, every sub-district area 30m
2Guard row is established in the minizone, in case the mutual interference of medicament phase.Test is adopted IX one 16 type sprayers to carry out cauline leaf and is sprayed, and evenly spray is distributed on capsicum cauline leaf, the fruit.Carried out field state of an illness investigation on the 7th day behind the medicine, 5 point sampling random sampling are adopted in investigation, and a situation arises for the investigation pepper anthracnose, 50 fruits of every sub-district investigation, and the sick fruit of classification numeration number calculates diseased fruit rate, disease index and control efficiency.2～3d adopts ocular estimate to investigate each sub-district to have or not poisoning to produce after each dispenser.
Stage division:
0 grade: no scab;
1 grade: lesion area accounts for below 2% of fruit area;
3 grades: lesion area accounts for the 3%-8% of fruit area;
5 grades: lesion area accounts for the 9%-15% of fruit area;
7 grades: lesion area accounts for the 16%-25% of fruit area;
9 grades: lesion area accounts for more than 25% of fruit area.
To look into diseased fruit rate (comprising shedding) during each the investigation
Disease refer to the preventive effect computational methods with biological Examples 4.
Result of the test shows: formulation embodiment 5 (20% bromothalonil pyraclostrobin aqueous emulsion) has good preventive effect to pepper anthracnose, tests each processing horizontal preventive effect a little more than the contrast medicament, and test does not see that crop and beneficial organism are had harmful effect.
Each processing of table 5 is to the preventive effect of pepper anthracnose
Biological Examples 6 composition for preventing and controlling plastic tent cucumber anthracnose field trials
Test is located in the cucumber booth, and cucumber variety is that grind No. one in Tianjin.The passageway is experimental field arranged in the middle of the booth, every limit plantation cucumber, width is 5m, and experimental field soil fertility is medium, and the cultivation management condition is good.Test is provided with formulation embodiment 9 (37.5% bromothalonil SSF 126) suspending agent 300,420,480g/hm
2, 25% bromothalonil missible oil 800g/hm
2, 25% SSF 126 suspending agent 300g/hm
2Adopt district's group arrangement at random, every processing 4 sub-districts amount to 24 sub-districts, every sub-district area 5m * 6m=30m
2Guard row is established in the minizone, in case the mutual interference of medicament phase.IX one 16 type sprayers are adopted in test, and every sub-district spray amount is that 3L carries out cauline leaf and sprays, and evenly spray is distributed in the cucumber leaves positive and negative.Behind medicine, carried out field state of an illness investigation in 7 days, 5 samplings in every sub-district, every some investigation 2 strains, statistical data is also calculated preventive effect.Grade scale and preventive effect computational methods are with biological Examples 4.
Result of the test shows: test medicine is respectively handled preventive effect all apparently higher than the contrast medicament, the control efficiency that has obviously improved after bromothalonil and SSF 126 are mixed cucumber anthracnose is described, to cucumber safety.
