Abstract
The invention provides a method for slowly releasing and applying tobacco rust control chemical, which is characterized in that: tobacco rust control chemical is split charged into a cylindrical cap to be made into a slow releasing cap after being incorporated into a slow releasing medium, and then the slow releasing cap is clasped round a diagonal plane of a topped stalk of the tobacco plant. Due to the adoption of the method, the application of the tobacco rust control chemical is free from being influenced by the weather, the tobacco rust can be effectively prevented from spreading during the entire mature period of the tobacco leaves, time and labor can be saved, the application efficiency of the farm chemical can be improved, the environmental pollution caused by the farm chemical can be reduced, and guarantee can be provided for the safety of the tobacco leaves.
Description
Technical field
The present invention relates to the prevention and control field of Alternaria alternate, specifically is a kind of Alternaria alternate control medicament slowly-releasing application process.
Background technology
Alternaria alternate is a kind of serious plant disease that extensively betides cigarette district, the world, accounts for the 30-35% that the cigarette area is planted by China according to the annual rust onset area of estimation.Rust not only makes tobacco leaf incomplete, and scab still continues to enlarge in bake process, makes irregular, the blade became uneven of baking leaf color, and grade descends, and because interior quality is inharmonious, has reduced industrial use value.According to the pests occurrence rule of rust, the main employing in the control to plant the comprehensive preventive health measures that disease-resistant variety, chemical control and the reasonable cultivation step of enforcement combine.But because the Alternaria alternate disease-resistant variety seldom, rationally cultivation step is implemented and is difficult for putting in place, and the control Alternaria alternate still mainly relies on medicament to prevent and treat in actual leaf tobacco production.
In leaf tobacco production reality, the method that control Alternaria alternate control medicament all adopts agroatomizer to carry out foliage-spray is carried out, and under the normal condition, the tobacco leaf maturing stage need spray medicament 3-5 time, then need spray 7-10 time like the rainy time.Traditional application method because of wind, Exposure to Sunlight, the agricultural chemicals that causes of drenching with rain runs off and decompose and reach 60%～90% usually, therefore sprays repeatedly, dosage is doubled and redoubled, and causes huge waste and harm.But the hit rate of exploitation novel pesticide is very low, on average wants for 6～8 years, and is expensive also huge.Therefore, be conceived to the improvement of existing pesticide species processing formulation and prescription, new purposes is developed in the improvement of physical and chemical performance and application process, and particular importance just seems.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of existing pharmacy application method; Through research and field trial, a kind of medicament slowly-releasing application process of preventing and treating Alternaria alternate that a kind of science is practical, be convenient to field practical operation, reduction agricultural chemicals usage amount and recruitment, be easy to promote is provided.
A kind of Alternaria alternate control medicament slowly-releasing application process, said method are after Alternaria alternate is prevented and treated medicament and incorporated the slowly-releasing medium, divide to be filled to the column type cap and to process the slowly-releasing cap, and said slowly-releasing cap is buckled the Dai Zhiyan strain cane scarf place of pinching.
Alternaria alternate is prevented and treated medicament slowly-releasing application process as stated, specifically carries out according to following steps:
The preparation of A, slowly-releasing medium: the weight ratio according to agar powder and sterile water took by weighing in 1.5: 100～3: 100, sterile water is boiled the back add agar powder, and fully stirring and evenly mixing is dissolved in sterile water fully until agar powder, be cooled to 45 ℃～50 ℃ subsequent use;
The preparation of B, Alternaria alternate slow-releasing agent: calculate actual every strain medicament usage amount according to rust control pharmacy application concentration, average application times, proportionally rust is prevented and treated medicament and sneak in the slowly-releasing medium of steps A configuration subsequent use behind the mixing;
The making of C, slowly-releasing cap: adopt the waterproof soft material to process cylindrical cap; Cap interior diameter 1.5～2cm; High 8～the 12cm of cap; Utilize iron stand and funnel branch to be filled in the slowly-releasing cap Alternaria alternate slow-releasing agent for preparing, make medicament be filled to 2/3 o'clock of slowly-releasing cap volume and be as the criterion, treat that medicament cooled and solidified rear seal-cover is subsequent use;
Use in D, field: when field cigarette strain is pinched, open the Alternaria alternate slowly-releasing cap that has prepared, back-off to the cigarette strain cane scarf place of pinching.
Alternaria alternate control medicament slowly-releasing application process also comprises after step D as stated
Step: E, recovery: after the tobacco leaf results finish, the slowly-releasing cap is reclaimed, reuse after the sterilization.
Alternaria alternate is prevented and treated medicament slowly-releasing application process as stated; Said rust control medicament comprises 10% polyoxin, 40% dimethachlon, polyoxin and potassium sulphate mixture or dimethachlon and potassium sulphate mixture for internal-suction type Alternaria alternate control medicament.
Alternaria alternate is prevented and treated medicament slowly-releasing application process as stated, and when using 10% polyoxin as rust control medicament preparation Alternaria alternate slow-releasing agent, every kg slowly-releasing medium dissolves in 10% polyoxin 5g～8g.
Alternaria alternate is prevented and treated medicament slowly-releasing application process as stated, and when using 40% dimethachlon as rust control medicament preparation Alternaria alternate slow-releasing agent, every kg slowly-releasing medium dissolves in 40% dimethachlon 10g～15g.
Alternaria alternate is prevented and treated medicament slowly-releasing application process as stated, and when using polyoxin and potassium sulphate mixture preparation Alternaria alternate slow-releasing agent, every kg slowly-releasing medium dissolves in polyoxin 5g～8g, potassium sulfate crystal 10～20g.
Alternaria alternate is prevented and treated medicament slowly-releasing application process as stated, and when using dimethachlon and potassium sulphate mixture preparation Alternaria alternate slow-releasing agent, every kg slowly-releasing medium dissolves in polyoxin 10g～15g, potassium sulfate crystal 10～20g.
After using the present invention, do not need repeatedly to spray applied once; (every mu is reduced 2 of recruitments can significantly to reduce the agricultural chemicals recruitment; Amount to about 120 yuan of RMB), reduce the agricultural chemicals input cost, improve the agricultural chemicals availability; Reduce the agricultural chemicals environmental pollution, can reach more than 70% the relative control efficiency of Alternaria alternate.For example: in order to control the generation of Alternaria alternate, use the present invention, after handling through the Alternaria alternate slow-releasing agent; 60 days investigation experimental field Alternaria alternate disease indexs, normal medicament sprays 5 processing, and control efficiency is 50.41% relatively; Use the relative control efficiency of 3 processing of the present invention (the slowly-releasing medium is identical, and inherent medicament kind prescription is different) all above 70%, wherein; The relative control efficiency of slow-releasing agent of being furnished with polyoxin and potassium sulphate is the highest, reaches 86.90%.
Alternaria alternate control medicament slowly-releasing application process provided by the invention; Can make using of medicament of Alternaria alternate control not receive weather effect; Whole tobacco leaf effective spreading of prevention and control Alternaria alternate in the maturing stage, the time and labour saving, and can improve applications of pesticide efficient; Reduced the pollution of agricultural chemicals, for the tobacco leaf safety provides guarantee to environment.
