Abstract
The invention discloses a method for preventing and treating green spot of citruses by using wood vinegar. The method is characterized by comprising the steps: uniformly mixing 99% mineral oil, the wood vinegar and water, wherein in the uniformly-mixed medicated solution, the final concentration of the 99% mineral oil is diluted by 200 to 300 times, and the final concentration of the wood vinegar is diluted by 30 to 40 times; and spraying citrus fruit trees with the mixed medicated solution. Through mixing the wood vinegar and the mineral oil, the control effect on the green spot of the citruses is improved greatly, meanwhile, the consumption of agents is lowered greatly, and the cost is reduced; and by the method, the residual of chemical pesticides on crops can be effectively avoided, and the pollution to environments caused by the chemical pesticides is reduced. The method is low in cost, wide in source of materials, light in environmental pollution and harmless to human bodies, thereby having a very good popularization and application value.
Description
Technical field
The invention belongs to pest and disease control of fruit trees technical field, and in particular to prevent and treat citruss paper disk test using wood vinegar
Method.
Background technology
Paper disk test is a kind of important citrus disease, by the illusory ball algae (Apatococcus of the illusory ball Trentepohlia of Chlorophyta
Lobatus) caused by parasitic, there is yellow green point in their early stage on blade and fruit, gradually extends to surrounding later, is formed
Irregular speckle simultaneously mutually heals, and covers full leaf and whole fruit, and when air humidity is relatively low, scab considers shape to be worth doing in leprosy, to Citrus
Photosynthesis affect very big, and then have a strong impact on tree vigo(u)r, fruit quality and yield.Preventing and treating paper disk test relies primarily on chemical agriculture at present
Medicine, but chemopreventive effects are undesirable, and in addition, chemical pesticide is applied in a large number and can also bring Drug resistance and food safety etc.
Series of problems.It is therefore desirable to the prevention and controls of highly effective and safe are researched and developed for paper disk test.
Wood vinegar typically refers to product liquid that the dry distillation of wood obtains in the clarification stood and after isolating settled tar
Bronzing liquid, main component are acetic acid, phenols, water, and wherein organic composition acetic acid accounts for more than 10%.Wood vinegar extensively can be answered
For chemical industry, forestry, agricultural, animal husbandry, food processing industry and medical and health industry.Especially agriculturally obtain extensive
Using being primarily useful for soil improvement, promote the plant growing such as fruit and vegetables, improve fruit food flavor and quality, replace synthesis
Pesticide etc..The product have stronger sterilization, the function of antibacterial in higher concentrations；The breeding of miscellaneous bacteria can be suppressed at low concentrations, had
Have fungi-proofing, effect of insect prevention.Wood vinegar can neutralize nitrogen sulfur compound and use as deodorant；Wood vinegar is because containing many phenolic materials
Mass-energy sterilization, sterilization keep away insect and use as sterilization, anthelmintic.In developed country's organic agriculture cultivation, oneself is widely used.
The content of the invention
The purpose of the present invention is to provide a kind of low cost, the application that prevention effect is good, environmental pollution is little for problem above
The method that wood vinegar prevents and treats citruss paper disk test.
The technical scheme for being adopted for achieving the above object is：A kind of application wood vinegar prevents and treats the side of citruss paper disk test
Method：99% mineral oil, wood vinegar and water are mixed, in the medicinal liquid after mixing, 99% mineral oil it is final concentration of dilute 200～
300 times, the final concentration of of wood vinegar dilutes 30～40 times；Citrus fruit trees are sprayed with mixed medicinal liquid.
Described Citrus fruit trees are Fructus Citri Limoniae, Fructus Citri grandiss, Fructus Citri sinensiss, wide skin Citrus, Fortunella crassifolia Swingle, miscellaneous Citrus chachiensis Hort..
In above-mentioned technical proposal, using spray method, medicinal liquid is equably sparged on blade.
Proceed by when each young sprout blade of fruit tree is ripe and spray, sprayed per 8～15 days 1 time, company applies 2～3 times.
When paper disk test preventing and treating is carried out to the fruit tree that grows up, per plant of adult fruit tree sprays liquid measure every time for 0.8～1.2kg.
The inventive method is also suitable for the paper disk test preventing and treating of seedling, and the medicinal liquid prepared according to aforementioned proportion is to all leaves of seedling
Piece is sprayed, and sprays number of times and is determined according to practical situation.
The invention has the beneficial effects as follows：The wood vinegar preventing and treating not only substantially increased to Citrus paper disk test mixed with mineral oil
Effect, while drastically reduce the area the usage amount of medicament, reduces cost, also, the method can be prevented effectively from chemical pesticide and exist
Residual on crop, reduces pollution of the chemical pesticide to environment.Low cost, material source are wide, environmental pollution is little, to human body without
Evil, with good application value.

Evaluating drug：Field control effectiveness test result statistical table is as shown in table 2.By the statistical analysiss to field investigation result
The preventive effect difference between different experiments process is obtained, as shown in table 3, is as a result shown, 99% 30 times of 200 times+wood vinegar of mineral oil,
99% 300 times+wood vinegar of mineral oil 40 is ideal to the paper disk test prevention effect in citrus leaves again, is considerably better than and shines medicine
150 times of 20 times of agent wood vinegar and 99% mineral oil, under drug effect is obviously improved, and dosing and cost are obtained significantly
Drop.Do not find that medicament produces poisoning to citrus leaves in the range of test dose, the method can the popularization and application in production.
2 wood vinegar of table prevents and treats mandarin orange paper disk test result of the test statistical table
3 wood vinegar of table prevents and treats mandarin orange paper disk test result of the test
Significance test adopts poor (DMRT) method of the new multipoles of Deng Kenshi.
By carrying out preventing and treating the paper disk test test of pesticide effectiveness to mandarin orange summer shoot blade in field, it was demonstrated that 99% mineral oil 200-300
Again+30-40 times of prevention effect to mandarin orange paper disk test of wood vinegar uses 99% 300 times+wood vinegar of mineral oil 40 very well, in production
It is relatively inexpensive again.Carry out after preferably adopting spray method, fine day dew dry, after medicinal liquid is diluted, uniform spraying thoughtfully is tender in young sprout
Ye Shang.Proceed by when each young sprout blade of mandarin orange is ripe and spray, development occurs with the backsight state of an illness, per 10 days or so 1
Secondary, company applies 2～3 times, can effectively mitigate harm of the paper disk test to citrus leaves.
