Abstract
The invented built up agent of iprodione and chlorothalonil contains 1-85% iprodione and chlorthalonil of the total pesticide wt., the wt. ratio of iprodione to chlorothalonil is 1-10 : 1-10. It can be made into smoke agent, wettable powder, granules, dust agent etc, and is effective in preventing and treating virus disease of tomato etc. and is non poisonous.
Description
The invention belongs to technical field of pesticide, particularly a kind of iprodione and chlorothalonil compound agent.
In recent years; China's protection ground growing vegetables area enlarges rapidly, and is the fast-developing trend of continuation, because the special ecotope in protection ground helps infecting of disease and popular; so it is serious day by day that multiple diseases such as gray mold, downy mildew takes place, and become the limiting factor of vegetables high and stable yields.Wherein the loss that causes of the gray mold that causes with Botrytis cinerea is generally 20-30%, and severe patient can reach more than 50% even total crop failure, and it is not only domestic important disease, also is a kind of worldwide disease.And the chemical control of relevant gray mold is subjected to domestic and international agricultural chemicals circle attention always, the sixties are that the benzimidazole germicide of representative is succeeded in developing with the carbendazim, once played a significant role to preventing and treating all kinds of eliminating vegetable botrytis, but the drug-fast report of this series bactericidal agent is arranged after several years in succession, and genetics of resistance is very stable both at home and abroad; Middle nineteen seventies is that two Shen carboxylic acid imide fungicides of representative are succeeded in developing with the iprodione, improved gray mold chemical control level greatly, this series bactericidal agent not only has high selection toxicity to gray mold, and also have prophylactic treatment and interior absorption conduction, become the first-selected medication that prevents and treats gray mold.After but continuous several times was used, pathogen produced resistance to some extent, and its control efficiency to diseases such as gray molds obviously weakens.
The object of the present invention is to provide a kind of iprodione 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 iprodione and the chlorothalonil compound fumicants that can effectively prevent and treat diseases such as eliminating vegetable botrytis.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: iprodione and chlorothalonil compound agent, contain the iprodione and the tpn that account for gross weight 1-85%, and iprodione and tpn weight ratio are 1-10: 1-10.
Iprodione: tpn=1: 1-5.
This composite dose is fumicants, contains the iprodione 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 iprodione 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 iprodione 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 iprodione 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 the general production method in this field, and wherein the fumicants production process comprises successively: the material pulverizing process---with oxidant NH
4NO
3, cooling agent potter's clay is crushed to by 100 mesh standard sieves with cracker respectively; The mixing of materials operation---get and pulverize again after above-mentioned oxidant, cooling agent and the combustion adjuvant wood powder of formula ratio and medicine slightly mix, go into the abundant mixing of mixer then; Dry-pressing formed---material is put into the forming machine hopper, open tablet press machine compressing tablet packing and get product.Recording fumicants autoignition temperature mean value of the present invention with reference to fumicants products measure method is 133.9 degree, ignition temperature mean value 286.8 degree; Store 14 days relative resolution ratio＜% of iprodione, tpn＜3% in 54 ± 2 degree insulating boxs; Become cigarette rate iprodione 81-84%, tpn 82-85%.
Product of the present invention is mainly used in control tomato gray mould, stalk break, gray mold of cucumber, leek gray mold etc.When fumicants used, according to warm canopy canopy chamber size, smoke point was put in laying, takes out smoked sheet, directly lighted to get final product, and using dosage is by former medicine 30-45 gram/mu, and dispenser in 7-10 days once.Because inflammable, the low toxicity of this product and eyes and skin are had minimal irritation should place shady and cool dry place, and stow away from heat and people and animals' food, feed.
Contained iprodione has high selection toxicity to gray mold in the product of the present invention, and prevention, treatment and interior suction conduction are arranged, and tpn is the broad spectrum type protective fungicide.The two composite use has positive effect to control eliminating vegetable botrytis etc.Fumicants provided by the invention is not only easy to use, and because flying away of soot dust granule improved medicament greatly at the plant surface coverage, also can overcome wetting powder and provide the weakness of advantage for pathogen infection because of improving leaf table microclimate relative moisture, therefore not only but maximum constraints is brought into play the prophylaxis effect of bactericide, and can reduce dosage.
Utilizing the present invention's 15% composite fumicants to prevent and treat the graw mold of tomato field test results shows; during starting, protection ground graw mold of tomato restrains former medicine/mu dosage by 30-45; continuous dispenser in 7 days is 3 times at interval, and control efficiency reaches 86.2%, obviously surpasses iprodione and the agent of tpn list.
Utilizing the former medicine of 90% iprodione (Jiangsu Rudong insecticide factory), the former medicine of 92% tpn (favorable to the people chemical plant, Xinyi) and 15% iprodione and chlorothalonil compound fumicants to botrytis cinerea---Botrytis cinerea bacterium (Shenyang Chemical Engineering Inst pesticide bioassay center cultivate) carries out the toxicity test result and shows: iprodione, tpn are to the EC of Botrytis cinerea
50Be respectively 2.247mg/L and 14.975mg/L, illustrate that the former is higher than the latter by bacteriostatic activity.15% iprodione and chlorothalonil compound fumicants co-toxicity coefficient reach 191.4, illustrate that iprodione and tpn have synergy, and synergy is obvious.
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 15% composite fumicants
50(median lethal dose, down together)＞4640mg/kg; Acute dermal toxicity, male, female rats LD
50＞2150mg/kg; Eye stimulates slight; Acute skin irritation is slight; Acute toxicity on inhalation, male, female rats LC
50(median lethal concentration, 2h)＞2150mg/M
3Unite acute toxicity evaluation criterion in " the chemistry security toxicological evaluation program " issued according to the Ministry of Public Health, the Ministry of Agriculture, belong to the lower toxicity agricultural chemicals.
In composite dose of the present invention, adopt the lower and prescription that tpn content is higher of iprodione content both can satisfy preventive effect and require to reduce product cost, economical and practical.
Further specify the present invention below by embodiment.
