Abstract
The invention relates to a composition used for controlling plant diseases. The effective components of the composition are iprodione (A) and an active component hymexazol (B), wherein a mass ratio of A to B is 100:1-1:100. When A and B are combined, a synergistic effect is provided for fusarium wilt controlling. Also, the composition can be used for controlling plant threadworms. The composition can be used in disease controlling of plant living bodies such as fruit trees, vegetables, alimentary crops, oil crops, sugar crops, cotton and bast fiber crops, and gardening plants, or growth sites thereof. Especially, the composition is used for controlling nematodiasis, fusarium wilt, and root rot.
Description
Technical field
The present invention relates to a kind of controlling plant diseases composition, especially a kind of composition that contains the controlling plant diseases of iprodione.
Background technology
Fusarium wilt is the disease of a kind of very refractory on the crop, for Deuteromycotina point sickle spore bacterium (Fusariumoysporum) causes, takes place generally often to cause the crops heavy losses.
Plant nematode mainly comprises: Meloidogyne (Meloidogyne), kidney shape Turbatrix (Rotylenchulus), cyst roundworm (Heterodera (Heterodera)), root spot nematode (Pratylenchidae belongs to (Pratykenchus)).Directly searching for food of nematode can significantly reduce plant to nutrition and absorption of water, and the nematode plant that searches for food is caused wound, returns the phytopathogen invasion and provides convenience.Calendar year 2001s such as Li Maosheng discover that root-knot nematode increases the weight of fusarium wilt and take place.
Hymexazo has good active to sickle-like bacteria, but the better prevention fusarium wilt is invalid to root knot nematode disease.
Summary of the invention
The objective of the invention is to: provide and use on a kind of suitable agricultural, fusarium wilt, nemas, root rot etc. are had safe, the efficient composition that contains iprodione of outstanding control efficiency.
The unexpected iprodione of finding of inventor is with the composition of hymexazo has synergistic effect when preventing and treating fusarium wilt; And can effectively prevent and treat root knot nematode disease and root rot; Can obtainable control efficiency compare with only using independent active component, mixing to use provides better control efficiency to fusarium wilt.
The present composition has synergistic function to fusarium wilt; And can effectively prevent and treat nematodosis; Therefore and be specially adapted to prevent and treat wilt and parasitic nematode, especially fruit tree, vegetables, oil crop, sugar [yielding, the linen-cotton class crop of harm plant, fusarium wilt and the parasitic nematode in the class plant of gardening gardens.
A kind of controlling plant diseases composition provided by the invention, (A) is with hymexazo (B) to it is characterized in that comprising iprodione; Even a small amount of A or B realize that for fusarium wilt Synergistic also is enough, and can effectively prevent and treat crop fusarium wilt and root knot nematode disease.A and B mass ratio are 100: 1-1: 100, preferred 50: 1-1: 50, most preferably 10: 1-1: 10.
The present composition can be prevented and treated nemas, fusarium wilt and the root rot of various crops such as cotton, vegetables (like cucumber, beans, tomato, potato and cucurbitaceous plant), banana, coffee, corn, fruits, rice, wheat, barley, oat, rye, soybean, peanut, ornamental plants, sugarcane etc.
The present composition is particularly suitable for preventing and treating nemas, crop fusarium wilt and root rot; Preferably the present composition is used to prevent and treat nematodosis and fusarium wilt, the root rot of oil crop such as cereal crops, fruit tree, cotton, vegetables, soybean and peanut, flowers and other crops, like wheat root-knot nematode and cyst roundworm, oranges and tangerines root-knot nematode, cucumber root-knot nematode, soy bean cyst roundworm, capsicum root-knot nematode, peanut root-knot nematode, watermelon blight, cucumber fusarium axysporum, tomato wilt, banana blight, capsicum root rot, cucumber root rot etc.
The present composition can be prepared into known method and be fit to the formulation that agricultural is used, and the total content of active ingredient is 0.5%-98% in the preparation, preferred 5-80%, and all the other are the pesticide adjuvant composition.
Can agricultural chemicals cooperative compsns of the present invention be formulated as the suspending agent of spraying after can supplying to dilute or carrying out soil or seed treatment, aqueous emulsion, microemulsion, missible oil, wetting powder, water dispersible granules, suspension seed-coating agent, microcapsule formulations etc., also can be made into granule and directly use.
Control crop fusarium wilt and nematode preferred dosage form are granule and suspension seed-coating agent.
Said preparation all can prepare with known method, for example prepares through active component is mixed with solvent and/or carrier, if the words that need are used other pesticide adjuvant compositions such as emulsifier and dispersant.
Insecticide-applying way can be taked spraying, irritates root, soaks root, seed soaking, dress seed, get rid of and execute, spread fertilizer over the fields, ditch spread, spread manuer in holes etc., preferred ditch spread, spreads manuer in holes, irritates soil treatment such as root or soak root, seed soaking, seed dressing and handle.
Compared with prior art, the beneficial effect of present composition generation is: (1) is compared with single agent, and is obvious to wilt synergy, improved control efficiency; (2) can significantly reduce the field dosage, reduce the possibility that causes poisoning, toxicity, reduce and produce and use cost, and can effectively reduce environmental pollution and residue of pesticide; (3) mechanism of action of active ingredient is different in the composition, has reduced the single selection pressure to wilt, helps overcoming the generation of wilt resistance and delays the drug-fast generation speed of wilt; (4) composition has good control efficiency to all kinds of nematodosis simultaneously;
Embodiment
In order to make the object of the invention, technical scheme and advantage clearer, the present invention describes with following specific embodiment, but the present invention is only limited to these examples absolutely not.
The synergistic function of the present composition can be explained through following test:
The biologicall test instance: iprodione is Yu the composite toxicity test to withered germ of water-melon of hymexazo
Subjects: withered germ of water-melon (Fusarium oxysporum f.sp.nixeum)
Test is with reference to " pesticide bioassay technology " (old spring chief editor, publishing house of Beijing Agricultural University publishes), and growth rate method (Plating) is adopted in " agricultural chemicals indoor bioassay test rule NY/T1156.2-2006 " this test.On the basis of preliminary experiment; On the sterile working platform, handle the sterilising medium that will melt in advance according to test and quantitatively place in the aseptic conical flask, from the low concentration to the high concentration, get the 5ml soup successively and join respectively the hot medium of 45ml (PDA medium is housed; 45-50 ℃) conical flask in; After shaking up, pour diameter 90mm glass culture dish rapidly into, each culture dish is poured band medicine medium 10ml into.Level leaves standstill, and processes flat board after the cooling.Five repetitions of each concentration.Blank is made in processing not contain the medicament effective ingredient.Be placed on after the processing in 26 ± 0.5 ℃ the constant temperature aseptic culture case and cultivate, take out behind the 7d.Adopt the right-angled intersection method to measure the colony diameter (is unit with the millimeter) that each is handled respectively, calculate the mean value and the inhibiting rate of colony diameter
The expection effectiveness of mixture of active principles (be theoretical control efficiency, %) confirm and compare with observed effectiveness by use Colby formula.
Colby formula: E=X+Y-X*Y/100
E: the active components A working concentration is a in composition, and the compositions contemplated when active component B working concentration is b is renderd a service,
X: the effectiveness when the active components A test dose is a,
Y: the effectiveness when active component B test dose is b.
Explanation has synergistic effect when observed control efficiency surpasses the expection preventive effect, and toxicity test result is referring to table 1,2.
