Abstract

The invention discloses a pesticide composition for preventing and curing cucumber downy mildew. The pesticide composition comprises three fungicides, namely, chlorothalonil, azoxystrobin and cyazofamid, and is used for preventing and curing the cucumber downy mildew by adopting a compound preparation. The pesticide composition has complementarity, an internal absorbing drug and a protective drug are mixed for use to form multiple acting sites, and thus a target is unlikely to have drug resistance. As the three fungicides are mixed for use, the control range can be enlarged, the preventive treatment effect is enhanced, the drug toxicity is lowered, the optimum drug application period is prolonged, the preventive treatment cost is saved, the drug application frequency is reduced, the adaptation property is reinforced, and the generation of the drug resistance of the target is delayed.

Description

The composition pesticide of control cucumber downy mildew
Technical field
The present invention relates to a kind of sterilization pesticide, especially a kind of composition pesticide of preventing and treating cucumber downy mildew.
Technical background
Cucumber downy mildew is a kind of common disease, all can fall ill in seedling stage, the one-tenth strain phase of cucumber.Gently then influence the cucumber normal growth and grow, heavy then cause the serious underproduction in the production, influence cucumber quality.And this disease has infectivity, infects characteristics such as fast, that development is rapid, wayward.Produce at present and go up the main pesticide controls such as carbendazim, tpn, Du Pont's gram dew, ethyl phosphine aluminium of using, they or single because acting on, do not have due therapeutic action, mainly acting on as " tpn " is the prevention fungal infection, inhale conduction in not having, the germ that does in the object for intrusion can't kill; Or because resistance strengthens, the lasting period is short, as " carbendazim ", " ethyl phosphine aluminium ", though interior absorption is good, result for the treatment of is obvious, easily produces resistance, reduces drug effect; And " 72% gram reveal " though can play and prevent and treat purpose, and the useful effect phase is short, and relative cost is higher, and vast farmers is difficult acceptance.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of instant effect is provided, property of medicine longer duration, the composition pesticide of the control cucumber downy mildew that control efficiency is good.
Technical problem to be solved by this invention is achieved through the following technical solutions.
A kind of composition pesticide of preventing and treating cucumber downy mildew is characterized in that, it comprises the active ingredient of following weight parts proportioning: tpn 7-11 part, Fluoxastrobin 2-4 part, cyanogen frost azoles 0.5-1.5 part.
As a kind of improvement:
The composition pesticide of described control cucumber downy mildew, it comprises the active ingredient of following weight parts proportioning: tpn 8-10 part, Fluoxastrobin 2.5-3.5 part, cyanogen frost azoles 0.8-1.2 part.
As further improvement:
The composition pesticide of described control cucumber downy mildew, it comprises the active ingredient of following weight parts proportioning: 9 parts of tpns, 3 parts of Fluoxastrobins, 1 part of cyanogen frost azoles.
Employed all raw materials are the commercially available prod among the present invention.
It is simple to adopt composition pesticide of the present invention to prepare the method for agricultural chemicals, and this composition pesticide and mixed with excipients are evenly made.
Using method: at premorbid or their early stage, every mu of use contains the agricultural chemicals of this composition pesticide 15~30 grams, adds 40~50 kg of water and mixes, and spraying is used.
The present invention compared with prior art has following good effect:
Tpn is wide spectrum, protectiveness low toxicity bactericide.The various crop fungal disease had prevention effect.Can with the fungal cell in glyceraldehyde 3-phosphate dehydro-genase have an effect, with the combined with protein that contains cysteine in this enzyme body, the vigor of destructive enzyme is damaged and loss of life power fungal cell's metabolism.The main effect of tpn is to prevent that plant is subjected to the infringement of fungi.Be mainly used in waiting fungal diseases such as rust on the plant, anthracnose, powdery mildew, downy mildew control.
Fluoxastrobin is new and effective bactericide, has protection, treats, roots out, infiltration, systemic activity.The mechanism of action mainly is to suppress mitochondrial respiratory, namely shifts by electronics between cytochrome b and C and suppresses mitochondrial breathing.Extranuclear mitochondria mainly by breathing to cell provides energy (ATP), if mitochondrial respiratory is obstructed, can not produce ATP, and cell will be dead.The bactericide that acts on mitochondrial respiratory is more, but with all bactericide were all different in the past, therefore control has special efficacy to the bacterial strain of sterol inhibitor (sterolinhibitors), phenylic acid amine (phenylamides), dicarboxylic dihydrazides amine (dicarbox-imides) and benzimidazole (benzimidazoles) generation resistance as the position (cytochrome b) of the Fluoxastrobin compound effects of methoxy acrylic.Nearly all mycota (Ascomycotina, Basidiomycotina, Mastigomycotina and Deuteromycotina) disease such as downy mildew, powdery mildew, rust, glume blight, net blotch, rice blast etc. all there is good activity.
Cyanogen frost azoles is the sulphaguanidine azoles fungicide, is a kind of super protective fungicide, to downy mildew, and eqpidemic disease, club root, damping off etc. have special efficacy.Mechanism of action is the supply that the electronics transmission of mitochondrial cytochrome b c1 complex in the blocking-up Oomycete germ body comes interfering energy, and its binding site is the Q1 center of enzyme, does not have cross tolerance with other bactericide.Plasmodiophora brassica bacteria to Oomycete fungi such as downy mildew, false downy mildew, phytophthora, pythium spp and Plasmodiophoromycetes has very high biologically active.
Tpn, Fluoxastrobin and cyanogen frost azoles are mixed and made in proportion, have complementarity, behind interior absorption medicament and the protectiveness pharmacy mix, form a plurality of action sites, target is not easy to develop immunity to drugs.During cucumber produces, multiple pest exists simultaneously often, and three kinds of bactericide mix to use and can enlarge control range, strengthen control efficiency, reduce medicament and poison, prolong the optimum period for applying fertilizer, save the control cost, reduce spraying times, strengthen conformability, delay the drug-fast generation of target.
Through us conscientious experimental study and analysis, patent of the present invention has following seven distinguishing features:
1, this product main body medicament mechanism uniqueness, combination science, only road innovation that is mixed are had complementary advantages significantly.
2, fungicidal spectrum is wide: medicine Zhiduo County disease, reduce dosage, and reduce production costs.
3, increase disease resistance: few morbidity, growing way is prosperous, early growth and quick tiller, listing ahead of time, price height.
4, improve resistance against disadvantage: weather is bad also can high yield.
5, delay senility: elongate harvest time, increase gross yield, improve total revenue.
6, the lasting period is long: 15 days special efficacy phases, reduce the medication number of times, and residue of pesticide are few, high quality and favourable price oversold money.
7, highly effective and safe: the strong osmotic effect of interior suction is obvious, and safety low-poison nuisanceless, the prospect of marketing is wide.
