13.6g a.i./hm2, 50% captan wettable powder 136.4g a.i./hm2Preventive effect compares, and synergistic effect is significant.Pass through
To 10 days preventive effect significance difference analysis after the 2nd medicine, embodiment chemicals treatment and comparison medicament processing preventive effect difference are reached and are extremely shown
It writes horizontal.
Security survey to tomato is observed after spray for several days after the 1st day and medicine, and each test process is to tomato without phytotoxicity
Phenomenon occurs.
Biological Examples 2: prevention and treatment sclerotinia sclerotiorum field trial.
Example of formulations 7 (33% isopropyl metsulfovax captan suspoemulsion), system have been carried out in Shaanxi Province's Hanzhong City within 2018
Agent embodiment 9(33% isopropyl metsulfovax captan aqueous emulsion), example of formulations 11(33% isopropyl metsulfovax captan micro emulsion
Agent) prevention and treatment sclerotinia sclerotiorum field trial, demonstrate control efficiency of the medicament to sclerotinia sclerotiorum and the safety to rape.
Trial crops are rape, controlling object be sclerotinia sclerotiorum (Sclerotinia sclerotiorum).Test is located at Hanzhong City
Yang County Huayang town, experimental plot topography is flat, and soil is yellowish-brown loam, middle fertility, pH value 7.1, during test in fertilizer and water management
Deng.See Table 6 for details for test medicine and dosage.Separately set blank control, 4 repetitions of every processing, every 40 ㎡ of cell, random district's groups arrangement.
Using conventional spray-on process, mu is administered liquid 45kg, is uniformly sprayed at leave dual sides.
Investigation and statistical method: investigating state of an illness radix before application, 10~14d is reinvestigated once after last time is administered, altogether
Investigation 2 times.10 points of every cell checkerboard type investigation, every is investigated 5 plants, and when investigation is careful not to sample in side row.Stage division:
0 grade: disease-free spot；
1 grade: slight morbidity, onset area account for 5% or less stem surface area；
3 grades: slight morbidity, onset area account for the 6%~15% of stem surface area；
5 grades: medium morbidity, onset area account for the 16%~30% of stem surface area；
7 grades: height is fallen ill, and onset area accounts for the 31%~50% of stem surface area；
9 grades: serious morbidity, onset area account for 50% or more of stem surface area.
Disease index=[∑ (diseased plant numbers at different levels × opposite value of series)/(investigating total strain the piece number × 9)] × 100
Control efficiency (%)=[1- (disease index after disease index × processing application before control is administered)/(state of an illness refers to after control application
Disease index before number × processing is administered] × 100
Table 6 prevents and treats sclerotinia sclerotiorum field test results
Table of field test results are bright, and 7,9 and 11 pairs of sclerotinia sclerotiorums of example of formulations have good control efficiency, by 180g
a.i./hm22 times spraying, 10 days preventive effects are above 30% after the 2nd medicine, with 36% isopropyl metsulfovax suspending agent of comparison medicament
16.4g a.i./hm2, 50% captan suspending agent 163.6g a.i./hm2Preventive effect compares, and synergistic effect is significant.By to the 2nd
10 days preventive effect significance difference analysis after secondary medicine, embodiment chemicals treatment and comparison medicament processing preventive effect difference reach extremely significant water
It is flat.
Security survey to rape is observed after spray for several days after the 1st day and medicine, and each test process is to rape without phytotoxicity
Phenomenon occurs.
In addition to above-mentioned graw mold of tomato and sclerotinia sclerotiorum, above-mentioned example of formulations is to pear scab and ring rot of apple
With synergistic effect.
Above embodiments explanation, the first active constituent isopropyl metsulfovax and the second active constituent captan are by weight 1:70
~70:1 compounding, can be made into wettable powder, water dispersible granules, suspending agent, suspoemulsion, aqueous emulsion, micro-emulsion form, to crop
Gray mold, sclerotiniose, scab, ring spot have significant control efficiency, and synergistic effect is obvious, and dosage is few, control efficiency is high,
And it is good to crop safety.
In conclusion composition of the invention is using two kinds of active components compound scheme, activity and bactericidal effect are not
It is the active simple superposition of each component, compared with existing single formulation, other than with significant bactericidal effect, more has significant
Synergistic effect, it is good to crop safety, meet the security requirement of pesticidal preparations.
