Abstract
The present invention relates to a compounded preparation of diethofencarb and chlorothalonil, which belongs to the technical field of pesticides; the present invention contains diethofencarb and chlorothalonil accounting for 1 to 85% of the total weight, and the compounded preparation comprises 1 to 10 shares of diethofencarb and 1 to 10 shares of chlorothalonil by weight proportion. The present invention can be prepared into various preparations of smoke preparation s, wettable powders, granule preparations and powder dust preparations, and has obvious prevention and cure effects on viruses of grey moulds, etc. of vegetables of tomatoes, etc. and no toxic hazard functions.
Description
The invention belongs to technical field of pesticide, mould prestige of particularly a kind of second and chlorothalonil compound agent.
Eliminating vegetable botrytis is one of important disease that influences yield of vegetables, and the chemical control of relevant gray mold is subjected to domestic and international agricultural chemicals circle attention always.From latter stage in the sixties is that to succeed in developing middle nineteen seventies be that the dicarboximide fungicide of representative is succeeded in developing with the Sukeling for the benzimidazole germicide of representative with the carbendazim, improve gray mold greatly and prevented and treated level, but these bactericide pathogen after use has all produced pesticide resistance to some extent, thereby its control efficiency to gray mold is obviously weakened.
The object of the present invention is to provide a kind of mould prestige of second and the chlorothalonil compound agent that can effectively prevent and treat diseases such as eliminating vegetable botrytis, its further purpose is to provide a kind of mould prestige of second and the chlorothalonil compound wetting powder that can effectively prevent and treat diseases such as eliminating vegetable botrytis.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: mould prestige of second and chlorothalonil compound agent, contain mould prestige of the second that accounts for gross weight 1-85% and tpn, and mould prestige of second and tpn weight ratio are 1-10: 1-10.
The mould prestige of second: tpn=1: 1-5.
This composite dose is fumicants, contains mould prestige of the second that accounts for gross weight 1-40% and tpn, 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 mould prestige of the second that accounts for gross weight 1-10% and tpn, also contains fillers such as potter's clay, the polishing surplus.
This composite dose is wetting powder, contains mould prestige of the second that accounts for gross weight 10-75% and tpn, 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 mould prestige of the second that accounts for gross weight 1-5% and tpn, 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.
Wherein the mould prestige ISO adopted name of second is diethofencarb, and chemical name is 3,4-diethoxy phenyl amido isopropyl formate, and structural formula is:
Empirical formula C
14H
21NO
4, 100.3 ℃ of fusing points, 25 ℃ of vapour pressures 1.46 * 10
-2Pa, the biological property sterilization; Tpn ISO general term chlorothalonil, chemical name 2,4,5,6-tetrachloro-1,3-dinitrile benzene, structural formula
Empirical formula C
8Cl
4N
2, fusing point 250-251 ℃, 25 ℃ of vapour pressures 5.72 * 10
-7Pa, the biological property sterilization.
Product preparation method of the present invention is that agricultural chemicals prepares universal method, wherein mould prestige of second and tpn wetting powder preparation method are: open mixer, successively former medicine, auxiliary agent (comprising wetting agent and dispersant), filler being added mixer fully mixes, open airslide disintegrating mill, the said mixture material is pulverized; Pack and get final product.
The present invention is mainly used in eliminating vegetable botrytis such as control tomato, 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 10-20 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.
The mould prestige of contained second belongs to systemic fungicide in the product of the present invention, and tpn belongs to the broad spectrum type protective fungicide, and the two composite use has obvious control efficiency to diseases such as eliminating vegetable botrytis.
Utilizing built wettable powder of the present invention to carry out the graw mold of tomato field control effectiveness test shows, mould prestige of 20% second and chlorothalonil compound wetting powder control graw mold of tomato, press mu dose dilution 500-700 doubly in morbidity phase beginning, spray in 7 days once at interval, connect and spray 3 times, preventive effect reaches 95.53%, and control obviously;
Adopt the former medicine of the mould prestige of 80% second (Xinyi insecticide factory product), the former medicine of 92% tpn (produce in favorable to the people chemical plant, Xinyi) and the present invention's 20% wetting powder to botrytis cinerea---Botrytis cinerea bacterium (cultivate at Shenyang Chemical Engineering Inst pesticide bioassay center) carries out the toxicity test test.Mould prestige of second and tpn are to the EC of Botrytis cinerea bacterium
50Be respectively 1.225mg/L, 13.266mg/L, the former the antibacterial latter of being higher than is described.Wetting powder co-toxicity coefficient of the present invention is up to 246.76, and illustrating that two medicines are composite has a remarkable 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 20% wetting powder
50(median lethal dose, down together)＞4640mg/kg; Acute dermal toxicity, male, female rats LD
50＞2150mg/kg; Acute skin irritation test, slight excitant; Eye stimulates, mild to moderate excitant.Unite acute toxicity evaluation criterion in " the chemistry security toxicological evaluation program " of promulgation by the Ministry of Public Health, the Ministry of Agriculture, belong to the lower toxicity agricultural chemicals.
Adopt the mould prestige content of second lower and prescription that tpn content is higher both can satisfy the preventive effect requirement among composite dose of the present invention, can reduce cost again, economical and practical.
