CN1349740A - Bactericide specially for preventing and treating diseases of tobacco in middle and later stage and its prepn - Google Patents

Abstract

The special-purpose fungicide for controlling several diseases in middle and later stage of tobacco plant growth is made up by using cupric hydroxide, Saikuzuo, Carboxymethyl cellulose, petroleum sodium carbonate, propanetriol, diatomite, isopropanol and chaku as raw material through a certain preparation process. Its finished product is a 55% wettable powder which can be used for curing wildfine, rust, angular leaf spot, powdery mildew, anthracnose and white rust, etc. Its preparation process is simple, does not produce waste water, waste residue and waste gas, and features low cost, broad spectrum, high efficiency and low-toxicity.

Description

A kind of bactericide specially of preventing and treating flue-cured tobacco middle and later periods multiple diseases and preparation method thereof

One, technical field

The present invention relates to technical field, be specifically related to a kind of bactericide of preventing and treating flue-cured tobacco middle and later periods multiple diseases with multiple diseases in the chemical method control flue-cured tobacco process of growth.

Two, background technology

Flue-cured tobacco long-term cultivated area in Yunnan Province's reaches ten thousand mu of 500-600, it is Yunnan finance pillar industry, its industrial profit accounts for about 70% of the whole province's fiscal revenues, prevents and treats the flue-cured tobacco disease owing to produce the medium-term and long-term agricultural chemicals such as the single dimethachlon of action characteristic, agricultural streptomycin, zineb, mancozeb, triadimefon that use.But, improvement along with working condition, the change of kind, ratio, quantity, method and flue-cured tobacco cultivars planting type and seedling raising manners of fertilising, transplant the climate and other natural phenomena of a season in advance, the former kind of flue-cured tobacco growth middle and later periods pathogenic bacteria, generation period, occurrence characteristic and harm also change thereupon.Prevent and treat to be difficult to gather effect with traditional medicament and method, because the ineffective economic loss that causes of disease control reaches hundred million yuans of 9000-1.1 every year, piece total crop failure in local field does not have and receives, and the flue-cured tobacco disease is seriously restricting Yunnan two cigarette high-qualitys and producing.

Because the mountain, Yunnan is how few, the restriction of arable land condition is difficult to accomplish efficent rotation, and the vega continuous cropping time is long, causes field cause of disease radix constantly to increase.Yunnan Flue-cured Tobacco middle and later periods disease has been a growth period by original more single disease species development and change over nearly 10 years, and cross-infection, common harm are taken place by fungi, bacterium various pathogens the former same period.The flue-cured tobacco middle and later periods, mainly based on wildfire, angular leaf spot, powdery mildew, rust, anthracnose harm, therefore, development was efficient, the medicament of wide spectrum and prevent and treat method, was to solve pressing for of serious plant disease.

Three, summary of the invention

1. goal of the invention

At the deficiencies in the prior art, provide a kind of wide spectrum, efficient, low toxicity, economy, safe, easy to use, the particularly bactericide specially that flue-cured tobacco middle and later periods multiple diseases is had good control efficiency.Simultaneously, the present invention also provides the preparation method of this bactericide specially.

2. technical scheme

The bactericide specially of control flue-cured tobacco middle and later periods multiple diseases, its component and content are:

Kocide SD 28%-62%

MBAMT 5%-28%

Diatomite 26%-36%

Carboxymethyl cellulose 2%-5%

Oil sodium carbonate 1.5%-3.5%

Glycerine 2.0%-6.0%

Isopropyl alcohol 1.0%-3.0%

All percentages of the withered 0.5%-1.5% of tea are percetage by weight.

Above-mentioned each component is made the preparation method of bactericide specially of control flue-cured tobacco middle and later periods multiple diseases, comprises the step of following order:

(1) with various raw material weighing, pulverize respectively, by 200 mesh standard sieves, standby;

(2) feed hydrogen copper oxide and MBAMT are obtained premix A and premix B respectively with after silicon bath soil evenly mixes, standby;

(3) premix A and B being added parts by weight respectively is 1.8 parts carboxymethyl cellulose, after fully mixing, obtains premix C and D, standby;

(4) premix C and D are mixed in proportion the back in the mixer running, it is withered that order adds oil sodium carbonate, glycerine, isopropyl alcohol, tea, obtains compound E after fully mixing, standby;

(5) compound E is levigate, cross 250 mesh standard sieves, fully mix again, through being up to the standards, packing, packing, promptly make the wetting powder finished product.

(6) quality standard is carried out by country and industry wetting powder standard.

3. beneficial effect

(1) the present invention is the applicant in long-term tobacco diseases study on prevention and production application, demonstration popularization process, according to the transition of the kind of Yunnan Flue-cured Tobacco disease, occurrence characteristic, harm situation with prevent and treat present situation and present Research both at home and abroad, succeed in developing on the basis of achieving success through the fields in 10 years and the big quantity research of indoor and outdoor, test, demonstration.In prescription and processing technology maturation, under the supporting prerequisite of application technology, province tobacco company has dropped into 1,360,000 yuan of funds, has demonstrated 280,000 mu continuously in the whole province's difference flue-cured tobacco cultivars and different ecological condition cigarette district, is subjected to the approval of relevant department and tobacco grower's welcome.

(2) the present invention is equipped with auxiliary agent through being processed into product with Kocide SD and MBAMT at home and abroad first, is used to prevent and treat the flue-cured tobacco middle and later periods, fungi and bacterial diseases such as wildfire, angular leaf spot, rust, powdery mildew, anthracnose.

(3) prove by indoor and outdoor prescription and action characteristic result of study: synergistic effect is extremely remarkable, and has wide spectrum, low toxicity, and is easy to use, resistance of rainwater washing against, and the lasting period reaches 12～28 days, has good preventing and result of treatment, and very strong practicality is arranged.And can continue the service life of single agent, delay cause of disease medicament is produced cross resistance.

(3) product processing technique of the present invention is simple, the raw material sources production domesticization, very abundant, do not have waste water, waste residue, waste gas in the production process, normal temperature was preserved 36 months down, and effective ingredient only reduces by 0.2%, meet national standard, processing cost and use cost are low, are convenient to preserve, transport, and are beneficial to environmental protection and reduce integrated cost.

(4) from the cigarette strain beginning dispenser for the first time of buddingging, to adopting roasting state of an illness use 1-2 time that finishes to look, concentration is 500 times of liquid sprayings, and use once 10-12 days interval, and integrated control effects such as the wildfire that take place period to this, angular leaf spot, anthracnose, powdery mildew, rust reach more than 90%.

(5) by the control in field demonstration continuous 4 years in Yunnan Province, in the cigarette district of 1100-2200 above sea level, to main breed, red big, K ₃₂₆, G ₂₈, cloud and mist ₈₅, V ₂Etc. kind, preventive effect is remarkable.The every mu of 60-85 unit that can retrieve economic losses, every mu is reduced control cost 21-32 unit, and ecological benefits, economic benefit and social benefit are obvious, have very strong applicability and good market prospects.
