Abstract
The present invention relates to a control method for tomato basal stem rot, aiming at solving the problems in the prior art that the control difficulty is increased and the control cost is increased as the drug resistance of bacteria is usually improved due to the fact that a pesticide is singly used for a long period. The control method is carried out according to the following manner: (1) carrying out soil ecological management; (2) carrying out agricultural control; (3) carrying out biological control; (4) carrying out biological prevention and treatment; (5) carrying out physical prevention and treatment; (6) carrying out chemical control: after transplanting and returning seedings, blending 150g of 58% metalaxyl*mancozeb with 100kg of water per mu, and irrigating roots once; and in 100ml of the water, dissolving 0.1-0.5g of chitosan oligosaccharide, 4-8g of hymexazol, 5-15g of lentinan, adding the water to dilute for 800-1000 folds, and then spraying. By virtue of the control method, the healthy and strong growth of plants is facilitated, the disease resisting capability of the plants is improved, the loss is reduced and diseases can be effectively prevented from occurring. The plants are treated when being not attacked so that the tomato pythium basal stem rot can be effectively prevented and treated.
Description
Technical field
The present invention relates to technical field of compounded pesticide, refer to a kind of prevention and controls of tomato base rot disease especially.
Background technology
Tomato base rot disease is the important disease in tomato production, delays in tomato planting in recent years generally occur at northern protecting field and autumn, causes total crop failure time serious.Tomato base rot disease is mainly caused harm basal part of stem or underground master root, and sick portion starts as crineous, and later around basal part of stem expansion one week, cortex rots, and overground part blade turns yellow, wilt, and the later stage, whole strain was withered, the sclerotium that the normal formation in surface, sick portion pitchy is not of uniform size.Germ survives the winter in soil, and can survive 2-3 in soil.Current prevention and controls, one is by ploughing deeply soil, the physical means such as vexed canopy of pouring water, and is exactly with nitrolim in addition, dislikes the Agro-chemicals controls such as mould spirit.But in production, single long-term prescription usually makes the raising of germ pesticide resistance, adds difficulty of prevention and cure and cost accounting.
Summary of the invention
The present invention proposes a kind of prevention and controls of tomato base rot disease, solves single long-term prescription in prior art and usually makes the raising of germ pesticide resistance, add the problem of difficulty of prevention and cure and cost accounting.
Technical scheme of the present invention is achieved in that
A prevention and controls for tomato base rot disease, it carries out in the following manner:
(1) soil ecology is administered, every mu of many No. 1 150ml of the fertile benefit of use, many No. 2 300ml of fertile benefit and many No. 3 100g of fertile benefit carry out soil treatment, application process, for adding fertile benefit many No. 1 150 milliliters and many No. 2 300 milliliters and stir of fertile benefit in 15 premium on currency, is placed 2 days under normal temperature; Add many No. 3 100 grams of fertile benefit afterwards, then place 1 day, add water to 250 kilograms, water root after stirring, whole breeding time uses 2-4 time;
(2) cultural control: select excellent resistant varieties; Select anosis, full, healthy and strong seed, cultivate anosis strong sprout; Carry out crop rotation in more than 3 years with non-solanaceous crops, deep plough simultaneously; Enhance field management, must guard against broad irrigation, find that ground temperature is too high, push the airing of basal part of stem soil aside;
(3) BIOLOGICAL CONTROL: strengthen the control to soil insect, reduces wound and infection; Strengthen field administration of health, weed a garden and the residual body of diseased plant, reduce pathogeny and invade channel;
(4) biological control, uses the 300 times of liquid sprayings of 0.3% polyoxin aqueous solution;
(5) physical control: nursery stage seedbed renews soil or with formaldehyde: potassium permanganate=2:1 is to soil disinfection; 55 DEG C of water logging kind 10-15 minute are first used, then with sowing after 0.1% potassium permanganate seed soaking during nursery; To note during field planting rejecting disease seedling, should not be excessively dark during Seeding planting, the rainy day gets rid of puddle in time, and ridging is unsuitable too high;
(6) chemical control, transplants after going back seedling, with 58% first frost MnZn 150 grams/acre, is watered double centner and fills with root 1 time; In 100ml water, dissolve in 0.1 ~ 0.5g amino-oligosaccharide, 4-8g dislikes mould spirit, 5-15g lentinan, then thin up 800-1000 doubly, spraying uses.
Preferably, in described step (6) in 100ml water, dissolve in 0.2 ~ 0.4g amino-oligosaccharide, 6-8g dislikes mould spirit, 6-12g lentinan, then thin up 800-1000 doubly, spraying uses.
Further, in described step (6) in 100ml water, dissolve in 0.3g amino-oligosaccharide, 7g dislikes mould spirit, 10g lentinan, then thin up 900 times, spraying uses.
Beneficial effect of the present invention: the present invention promotes that robust plant grows, improves the resistance against diseases of plant, reduces the loss, and can effectively occur by controlling disease.Process when not falling ill, can the generation of effective prevention and cure pythium stem base rot of tomato.
