Description
Technical field
The present invention relates to a kind of Prospect on Kiwifruit Bacterial Canker prevention and treatment composition pesticide and Prospect on Kiwifruit Bacterial Canker control methods.
Background technique
Prospect on Kiwifruit Bacterial Canker is Pseudomonas syringae pv.actinidiae (Psa；Pseudomonas syringae
Pv.actinidiae infectious disease caused by) is the fatefulue disease (Serizawa seriously damaged to Kiwi berry growth belt
Deng 1989).The Kiwi berry planting site of Jizhou Island in South Korea's the first explosion canker in 1988 is located at 150~250m's of height above sea level
The Chinese takes the mountain middle part of mountain half way up the mountain, due to being the area of winter freeze injury frequent occurrence, does not have any letter to canker
It is merely judged as freeze injury by the plant personnel of breath and experience, is abandoned and is planted Kiwi berry in this area.(Koh, 1995, Koh
And Lee, 1992).
Even if confirming that the bacterium for being referred to as Psa causes after Prospect on Kiwifruit Bacterial Canker (Angelo etc., 2012.5), if in ulcer
Sick outburst initial stage enough could not appropriately cope with, then can bring the serious damage for being enough to make orchard to close garden degree, therefore actual conditions
It is once outburst canker, many peasant households abandon plantation Kiwi berry.This is because including caused by the bacterium of Prospect on Kiwifruit Bacterial Canker
Phytopathy is once broken out, will be fast-developing in plant, and is easy to infect to other plant body outburst superinfection, because
This is very difficult to prevent and treat.(Kim etc., 2016a, 2016b；Son etc., 2016)
Until 2005, the female plant kind of dioecious Kiwi berry is largely that green Kiwifruit Cultivars are i.e. extra large in South Korea
Ward (Hayward) (Huang, 2014).Therefore, although canker is mainly broken out in Hayward, with since 2004
Canker, golden fruit are broken out since 2006 in golden yellow Kiwifruit Cultivars, that is, golden fruit (Hort16A) of Jizhou Island plantation
Also start be damaged (Koh etc., 2010).Kiwi berry is set to cause the Psa biovariety of canker in South Korea until 2010
(biovar) it is only Psa2, but started to bring bigger damage to golden fruit Kiwi berry and red kiwifruit kind since 2011
Since harmful Psa3 flows into South Korea, more serious damage has been brought to the peasant household of plantation golden fruit Kiwi berry and red kiwifruit kind
Evil, and spreading (Kim etc., 2016a, 2016b；Koh etc., 2012a).
In South Korea, since 1988, canker caused by Psa2 is only broken out between 20 years, but in South Cholla in 2011
Happiness prefecture earliest detection goes out Psa3 (Koh etc., 2012a), and detects Psa3, nearest South Korea since Jizhou Island in 2014
Canker caused by the whole region outburst Psa3 of main kiwifruit planting site.To the inflow way of the Psa3 quickly spread in South Korea
The result of the epidemiological survey of diameter, it is thus identified that in the Psa3 of discovery in 2011 be in 2006 by the infected sapling of China
Or grafting inflow, infer that the Psa3 spread since 2014 is flowed by the pollen polluted in New Zealand and China
(Kim etc., 2016b).Although the orchard of the outburst Psa3 of South Cholla happiness prefecture carried out closing garden by public prevention in 2014
Further diffusion is cut off in measure, but by import pollen flows into the quick-fried of canker caused by the highly pathogenic Psa3 of South Korea
Hair, causes the peasant household's number sustained damage until 2016, to increase every year twice from 2014, it is contemplated that the outburst and damage of canker
Evil will be increasingly severe.
Prospect on Kiwifruit Bacterial Canker starts to break out in the sap in late winter or early spring mobile first time phase, infers this is because freezing
Evil causes actinidia tree generation wound to play Psa's in the weather of frost free period low temperature and moisture to form the intrusion path of Psa
Predisposing factors effect (Ferrante and Scortichini, 2014；Ferrante etc., 2012).In Japanese outburst ulcer earliest
Disease county, Shizuoka and be Fuji and the Han Na of height above sea level 150m or more respectively in the Jizhou Island orchard that canker is broken out earliest in South Korea
Mountain half way up the mountain, and the high hilly country of the height above sea level for being easy to happen freeze injury positioned at winter (Koh, 1995；Koh and Lee, 1992；
Koh etc., 1994；Serizawa etc., 1989).In addition, in South Korea because of canker great outburst, the orchard that collective closes garden be located at Guan Dao,
Winter is because cold sea wind is easy to happen freeze injury and encourages the morbidity of Psa in the island area on precious island, the island happiness Jun Jujin etc.
Seashore (Ko etc., 2000a, 2000b, 2002；Koh etc., 2010).In addition, due to the foot of the hill, trench or basin also cold sky of stagnant winter
Gas and be easy to happen freeze injury, therefore Psa can be excited.
Psa, which has, can make it carry out ecological adaptable movable a variety of gene, therefore throughout the year easily
In invasion actinidia tree and cause to infect (Scortichini etc., 2012).Known Psa as gramnegative bacterium have 1~
2 flagellums are afraid of high temperature, winter daily mean temperature keeps will be slow activity at 0 DEG C or so, even if at 2~5 DEG C although happiness water
If lower persistently become a fine day can also cause canker, but break out seriously in cold and moist spring canker instead.At 2 months and
Such meteorological condition is conformed exactly between March, the period typical canker symptom is to flow out bacterium efflux from stem.
Bacterium efflux be to inside orchard or the most important infection sources of orchard external communication Psa (Schrizawa and
Ichikawa, 1993c；Serizawa etc., 1989,1994).In spring because of frequent rainfall, wetness is also high, temperature be 12~
At 18 DEG C, Psa proliferation is most fast (Serizawa and Ichikawa, 1993b), when growing leaf, positioned at the thin of actinidia tree surface
Bacterium efflux is moved to new stem (Serizawa and Ichikawa, 1993a) by petiole from infected leaf, infected
Sprout Psa by xylem and bast carry out it is mobile make canker deepen (Gao etc., 2016；Spinelli etc., 2011).
Start about 10~15 days before blooming, i.e., general mid-May, infecting the bud of canker, to show calyx brown
The symptom of change flows out transparent bacterium efflux from the calyx of part severe infections.In addition, bennet many places are infected, and withered
Bud, which is not bloomed, just to wither.But canker symptom is not observed in actinidia tree fruit, Psa is not also detected.
Later, temperature declines again, in the late October and 11 that the lowest temperature is 10 DEG C, the highest temperature is 20 DEG C or so
Month, travel to hole skin or hibernaculum by wind, rainwater, storm, irrigation water, shrub and hedge trimmer etc., so as to cause new infection (Gao etc.,
2016；Serizawa etc., 1994).In particular, comparing 16 DEG C or 25 DEG C, Psa is spread more quickly instead at 4 DEG C in branch.Greatly
Partial bacterial plant disease has very special generation ecology, i.e., breaks out in the environment of high temperature and humidity, and in sweltering heat
Summer hides (Son, Kyeong-In etc., phytopathy research, plant pathology association, 2016).
Problem is not constituted in initial planting Prospect on Kiwifruit Bacterial Canker, but as canker is broken out, is become and given plantation peasant household's band
Carry out the disease of the economic strike of most serious.According to the data of report, start the beginning of the eighties in California some areas, Japan
County, Shizuoka, some areas such as Kanagawn sharply break out, spread extremely serious to surrounding, be that extremely troubling can be damaged
Harmful disease.Confirmed according in Jizhou, between 87~88 years, by the Chinese take the backlands Shan Shan area centered on witnessed symptom, 91 years
Using whole orchards as object investigate as a result, actual conditions are that only in mountain backlands area, morbidity just reaches 14.9% and leads in 164ha
Induced damage resistive increases, and also continuously occurs closing the orchard in garden.
Milky~sap russet is oozed out from stem annual 2 months~April, leaf 2~3mm occurs in April~July
Brown~dun spot of left and right.Most cases are that the spot is turned yellow around with the width of 2~5mm or so.Once
After illness occurs in leaf, if winter beta pruning terminates, around bud or colored liquid is flowed out in the position of fallen leaves, beta pruning position
Or exudation white, flaxen bacterium block.Although the disease stops development with the temperature rises after May, germinates, blooms, result
Afterwards, because the tissue necrosis of wound part causes branch withered.
It is known that generally in the environment in orchard, because the clay loam soil for draining bad leads to the undesirable area of root development
Or radix saposhnikoviae it is bad lead to the trees by disaster caused by a windstorm, lead to be often subject to freeze injury because of high-land and cold calamity disaster caused by a windstorm more than place, in addition
Because being easy to appear damage when annual result excessively tree vigo(u)r is caused to die down, and using nitrogen or plant tissue growth crisp too much
It falls ill on weak trees more.
