Abstract
The invention discloses an application of a benziothiazolinone-containing chemical agent for prevention and treatment of potato black shank and a prevention and treatment method. For black shank in the process of potato growth, a 3% benziothiazolinone wettable powder is used for prevention and treatment, and thus the incidence rate of potato black shank is effectively reduced.
Description
Technical field
The present invention relates to a kind of preventive and therapeutic effect of chemical agent containing benziothiazolinone to blakleg of potato.
Technical background
Benziothiazolinone（Benziothiazolinone）Different thiazoles compound, is that a kind of efficient, low toxicity, broad spectrum activity are sterilized
Agent, its mechanism of action is：React with the anion binding of the surface of cell membrane of bacterium or with sulfydryl, destroy protein and cell membrane
Synthesis system, so as to suppress bacterial reproduction, disturb pathogen cell metabolism so as to physiologic derangement, cause pathogen dead
Die.The compound has good prevention effect to bacterial corps diseases, and fool proof to crops.
Potato is the world " the fourth-largest cereal crops ", and the potato planting area of China accounts for the whole world potato gross area
20%-25%, but its yield, quality potato seed quality be subject to pest and disease damage severe constraints.Blakleg of potato is to affect at present
One of main bacterial disease of potato seed growing area, blakleg of potato be byErwinia carotovora subsp.atrosepticaA kind of disease for causing, can be by the way such as the rainwater that carries disease germs, insect, irrigation water, steam fog, machinery, weeds and soil
Propagate in footpath.Effectively preventing method is the disease-free potato seed of plantation at present, but disease-free potato seed is still easily aggrieved in field planting.
As the continuous cropping phenomenon of potato planting increases, blakleg of potato is on the rise, and loss late reaches 3%-68%, bacteroidal
Balck shank also has black leg of cabbage, fish pelargonium balck shank, broccoli balck shank etc. except blakleg of potato, but the black shin of potato
Germ is different in presence in subspecies of causing a disease with other balck shanks, and people adopt some antibioticses medicaments and copper at present
The conventional medicament of the bacteriosises such as preparation carries out the preventing and treating of blakleg of potato, but possible germ for different pathogenic subspecies and dispensers
Mode is incorrect etc., and reason causes preventive effect undesirable, therefore the present invention is provided for the chemical prevention present situation of blakleg of potato
A kind of medicament for efficiently preventing and treating balck shank, and corresponding application method, so that lift Potato Quality.
The content of the invention
The technical problem to be solved provide containing benziothiazolinone chemical agent prevent and treat blakleg of potato and
Preparation prevents and treats the purposes on blakleg of potato medicine.
The chemical agent containing benziothiazolinone can be the single dose of benziothiazolinone, or any compounding that will not produce antagonism
Multiple active components agricultural chemicals.
Further, benziothiazolinone can be made into 3% benziothiazolinone wettable powder of mass percent to prevent and treat blakleg of potato.
Another technical problem to be solved of the invention is to provide a kind of method for preventing and treating blakleg of potato, and it includes
Following steps are at least one or whole two kinds：
For the potato crop that blakleg of potato does not occur, prevented with when sowing using following methods prior to seeding：
Seed dressing：3% benziothiazolinone wettable powder makes 30-35 times of solution（Concentration range）, spraying treatment potato seed, and stir potato seed
Each surface is made medicine uniform；With thiophanate-methyl and talcum powder（1:20）Being well mixed to mix is carried out in the potato seed surface of spraying treatment
Dry pack is pulled out, shady place is put in and is waited sowing；
Ditch spread：3% benziothiazolinone wettable powder 60g/ mus of seeder ditch spread are utilized in the potato sowing phase.
For the potato crop of potato-infecting balck shank, treated using following methods：
Foliar spray：Blakleg of potato early stage liquid sprays 3% benziothiazolinone wettable powder 80g/ mus, carries out second time spray after 7d,
3% benziothiazolinone wettable powder 80g/ mus.
Drip irrigation：3% benziothiazolinone wettable powder 150g/ mus of blakleg of potato early stage drip irrigation.
The present invention prevents and treats blakleg of potato using benziothiazolinone, shows that benziothiazolinone has substantially to P. carotovorum
Fungistatic effect, and using 3% benziothiazolinone wettable powder combine corresponding Drug level, insecticide spraying time and application method in Ma Ling
Significant effect is achieved in the preventing and treating of potato balck shank.

Specific embodiment
Test of pesticide effectiveness example
Embodiment 1, Toxicity Determination of the 3% benziothiazolinone wettable powder to blakleg of potato（Agricultural University of the Inner Mongol）
Test is carried out with reference to ＜ farm-chemical indoor determination test rule bactericide ＞.
3% benziothiazolinone wettable powder has obvious fungistatic effect, the horse that each dosage is processed to P. carotovorum
Bell potato black shank bacterium is suppressed, and with the increase of concentration, fungistatic effect strengthens, and drug concentration is in positive with bacteriostasis
Close, coefficient R2For 0.905, EC50It is worth for 30.82 g/ml（Table 1, Fig. 1）.
Blakleg of potato bacterium Toxicity Determination is carried out using conventional 46% Kocide SD of medicament of bacteriosis and finds 46%
There is no bacteriostasis to blakleg of potato bacterium in Kocide SD（Table 2, Fig. 2）.
Toxicity test result of the 1 3% benziothiazolinone wettable powder of table to balck shank germ, while also can be found in Fig. 1：
Toxicity test result of 2 46% Kocide SD of table to balck shank germ, while also refer to Fig. 2
Embodiment 2,3% benziothiazolinone wettable powder prevention blakleg of potato.
Test method：The potato wedges of 30-50g is cut into prior to seeding from the potato of health, each potato wedges carries eye, 3%
Benziothiazolinone wettable powder 150g is watered 5L, the potato seed of spraying treatment 1T, and stirring potato seed, to make each surface medicine uniform；Use 1kg first
Base thiophanate and 20kg talcum powder are well mixed to mix and carry out pulling out dry pack in the potato seed surface of spraying treatment, are put in shady place wait
Sowing.3% benziothiazolinone wettable powder 60g/ mus of seeder ditch spread are utilized in the potato sowing phase, using routine administration as control.
Grab sample investigation is carried out to each testing site in potato tiller phase and squaring period, each test clicks 5 points of tune
Look into, each point 100 potato plant of investigation, and calculate the incidence of disease.
Diseased plant rate（%）=（Morbidity stem number/total stem number）×100
