Abstract
A mixture of cymoxanil and chlorothalonil, as an agricultural chemical, in the form of smoking agent, wettable powder, particles and powder for preventing and treating the downy mildew of vegetables such as cucumbers with high effect, low cost and no toxic damage features that the weight ratio of cymoxanil and chlorothalonil in the mixture is 1-85% and the weight ratio of cymoxanil to chlorothalonil is (1-10) : (1-10).
Description
The invention belongs to technical field of pesticide, particularly a kind ofly can effectively prevent and treat the white urea cyanogen and the chlorothalonil compound agent of diseases such as vegetables downy mildew.
In recent years, great changes have taken place in China's rural area pattern of farming, and economic crops cultivated area growth rate is very fast, and particularly the development of vegetables and fruit cultivated area is very fast.Meanwhile, crop disease and insect generation area also increases year by year, and particularly because agricultural chemicals uses the damage by disease and insect resistance constantly to strengthen year after year, wherein the downy mildew of vegetables is that resistance increases comparatively fast, influences one of main disease of vegetable growth.Generally with tpn and mancozeb class wetting powder, but preventive effect is undesirable to its control, with Du Pont's gram reveal, peace gram MnZn preventive effect is better, but cost is higher.
The object of the invention is to provide a kind of can effectively prevent and treat the white urea cyanogen and the chlorothalonil compound agent of diseases such as vegetables downy mildew, and further purpose is to provide a kind of and can effectively prevents and treats the white urea cyanogen and the chlorothalonil compound wetting powder of diseases such as vegetables downy mildew.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: white urea cyanogen and chlorothalonil compound agent, contain the white urea cyanogen and the tpn that account for gross weight 1-85%, and white urea cyanogen and tpn weight ratio are 1-10: 1-10.
Frost urea cyanogen: tpn=1: 1-5.
This composite dose is fumicants, contains the white urea cyanogen and the tpn that account for gross weight 1-40%, also contains oxidant, combustion adjuvant, cooling agent and stabilizing agent.
Oxidant is nitrate such as ammonium nitrate, accounts for gross weight 10-35%; Combustion adjuvant is a wood powder etc., accounts for gross weight 10-35%; Stabilizing agent is an ammonium chloride etc., accounts for gross weight 1-8%; Cooling agent is potter's clay, land plaster etc., the polishing surplus.
This composite dose is dust agent, contains the white urea cyanogen and the tpn that account for gross weight 1-10%, also contains fillers such as potter's clay, the polishing surplus.
This composite dose is wetting powder, contains the white urea cyanogen and the tpn that account for gross weight 10-75%, also contains wetting agent, dispersant and filler.
Wetting agent is a neopelex, and dispersant is lignosulfonates, and the two accounts for the 5-20% of gross weight; Filler is a precipitated calcium carbonate, the polishing surplus.
This composite dose is granule, contains the white urea cyanogen and the tpn that account for gross weight 1-5%, also contains binding agent and carrier.
Binding agent is paraffin, polyvinyl alcohol etc., accounts for gross weight 1-5%; Carrier is sand, cinder etc., the polishing surplus.

Product preparation method of the present invention is that agricultural chemicals prepares universal method, and wherein white urea cyanogen and tpn wetting powder preparation method are: open mixer, successively former medicine, auxiliary agent (comprising wetting agent and dispersant), filler are added mixer and fully mix; Open cracker, the said mixture material is pulverized: pack and get final product.
The present invention is mainly used in the downy mildew of vegetables such as control cucumber, when its wetting powder uses, earlier medicament is poured in the sprayer, converts water then to stir, and the blade face evenly sprays.Using dosage is by 500-700 times of former medicine 12.5-25 gram/mu dilution, and dispenser in 7-10 days once.This product should be avoided and skin and eye contact, cleans as contacting immediately; Should be stored in shady and cool dry place, keep fire away, thermal source; Must not mix with food, feed and put.
Contained white urea cyanogen is systemic fungicide in the product of the present invention, and tpn is the broad spectrum type protective fungicide, and the two composite use has obvious control efficiency to diseases such as vegetables downy mildew.
Utilizing built wettable powder of the present invention to carry out the cucumber downy mildew field control effectiveness test shows, 25% white urea cyanogen and chlorothalonil compound wetting powder control cucumber downy mildew, by 500 times of mu dose dilution, morbidity beginning period interval spray in 7 days 1 time, connect to spray more than 3 times and can control its popular causing harm preferably, preventive effect reaches 88.3%, and to cucumber safety.It is suitable that 25% white urea cyanogen and chlorothalonil compound wettable powder dilution agent 500-700 preventive effect and 72% gram reveal 600 times of preventive effects of dilution.And from the control cost, 5.5 ten thousand yuan/ton of product 25% built wettable powders of the present invention, but and 72% gram dew wet-milling market price of du pont company production reaches 100,000 yuan/ton.
Adopt the former medicine of 98% white urea cyanogen (east, Tianjin insecticide factory product), the former medicine of 92% tpn (produce in favorable to the people chemical plant, Xinyi) and wetting powder of the present invention that bacterium of downy mildew of cucumber (cultivate at Shenyang Chemical Engineering Inst pesticide bioassay center) is carried out the toxicity test test, obtain each medicament toxicity index and mixture toxicity index, calculate co-toxicity coefficient.The result shows: white urea cyanogen, tpn and the present invention's 25% wetting powder are respectively 32.23mg/L, 156.35mg/L to downy mildew bacterial strain EC50,46.182mg/L, 25% mixture (wetting powder) co-toxicity coefficient is up to 191.26, proves that two medicaments are mixed and have the notable synergistic effect.
According to GB-15670-1995 " agriculture chemical registration toxicology test method " be: acute oral toxicity, male, female rats LD to the The acute toxicity tests of the present invention's 25% wetting powder
50(median lethal dose, down together)＞5000mg/kg; Acute dermal toxicity, male, female rats LD
