Compound and the preparation thereof that this patent is related to set forth the control of plant disease effect by the following examples.
4, the biological activity determination of each compound
Choose 6 kinds of pathogenic bacterias altogether as for the examination bacterial classification, list in table 4-1 for the examination bacterial classification.All provide by Nuisanceless Pesticide Research Service Center, Xibei Agroforestry Science and T for the examination bacterial classification.
The test plant host material: tomato Lycopersicon esculentum fruit, pick up from Yang Ling Yangchuan village township plastic greenhouse; Cucumber (grind No. seven in Tianjin), commercial.
Standard medicament: 50% ethyl phosphine aluminium WP, 50% Sukeling WP.
Table 4-1 is for the examination pathogenic bacteria
Growth rate method
Compound adopts growth rate method to the inhibiting mensuration of pathogenic bacteria mycelial growth, establishes acetone and blank, and every kind is a processing for examination bacterium one ware, and every processing repeats for three times.Measure colony diameter with the right-angled intersection method, calculate inhibiting rate (during the calculating inhibiting rate be contrast with the acetone treatment) by formula 4-1 and formula 4-2:
Colony diameter (mm)=bacterium colony mean diameter-4 (bacterium cake diameter) 4-1
The spore germination method
Above-claimed cpd adopts sessile drop method to the inhibiting mensuration of germ spore germination
[114]([114] Fang Zhongda plants disease research method [M], Beijing agricultural press, the third edition, 1995).In the test, after contrast sprouting (be sprouting with long short diameter one half of spore that surpasses of spore germ tube, if having little time microscopy, can add one in 0.5% mercuric chloride and fix) rate is greater than 80%, the sprouting situation of all processing of record check; If the contrast germination rate is lower than 80%, this test is cancelled and is reformed.Adopt formula (4-3) and (4-4) calculating spore germination inhibiting rate.
Pot experiment
Described each compound that the present invention relates to is mixed with cream preparation, carries out potted plant and rules of organization mensuration.
The prevention effect of cucumber downy mildew adopts the pot experiment method to carry out.Concrete grammar is as follows:
Sow 2~3 cucumber seeds of vernalization at every nutrition pot,, treat that cucumber grows to two leaves (true leaf), treats with provide protection and tests in hot-house culture. carry out dispenser with conventional spray, 3 repetitions are established in each processing, establish the contrast of solvent control and clear water.
Gather the sick leaf of the former bacterium of band cucumber downy mildew from the field, cultivate 24h with preserving moisture after the flushing with clean water, with the pathogenic bacteria spore on the sick leaf under the writing brush brush, be configured to that 30~50 spore suspensions carry out spray inoculation under 10 * 10 power microscope visuals field, the cucumber after the processing is placed in high humidity, about 20 ℃ the environment and cultivates.
Therapeutic action at first connects the germ spore on not processed seedling, spray medicine behind the 24h again and handle, cultivate.Check test result behind 6~8d; Provide protection is at first sprayed medicine to seedling and is handled, and connects bacterium behind the 24h again, checks blade incidence and record, statistical results behind cultivation 6~8d.
The grade scale of cucumber downy mildew (is unit with the blade) (Fang Zhongda plants disease research method [M], Beijing agricultural press, the third edition, 1995):
0 grade: anosis;
1 grade: lesion area accounts for below 5% of one-piece blade area;
2 grades: lesion area accounts for 6~25% of one-piece blade area;
3 grades: lesion area accounts for 26%~50% of one-piece blade area;
4 grades: lesion area accounts for more than 50% of one-piece blade area.
Calculate disease index and prevention effect by formula 5-5 and formula 5-6:
The tissue test method
The test of pesticide effectiveness to graw mold of tomato adopts tomato young fruit method to carry out.Concrete grammar is: the tamato fruit of not executing any bactericidal agent that will gather from the field, earlier with the clear water washes clean, dry, get 75% ethanol wiping fruit surface again with the absorbent cotton libation at an ancient wedding ceremony, carry out sterilising treatment.Sting out the zone of infecting of the about 5mm of diameter on the tamato fruit surface with inoculating needle, in order to infecting of ash arrhizus bacteria.Make the bacterium cake with the punch tool of diameter 4mm, the bacterium cake is tipped upside down on the tamato fruit surface.Divide protection and treat two kinds of methods processing.Provide protection is sprayed directly on fruit surface for adopt spray method will dilute good medicament earlier on the tomato surface, treats promptly to begin to connect bacterium after soup dries.Therapeutic action begins to connect bacterium for earlier the bacterium cake being connected on the tamato fruit surface behind the 4h.The cultivation of preserving moisture, check result behind the 3d.By the method among the 4.1.2.1 result is carried out statistical study.
