Abstract
The present invention is a kind of method of preventing and treating of corps diseases.With TCCA (sym-closene) as the agricultural bactericidal disinfectant, can carry out seed rice, cotton seed and multiple kinds of crops seed disinfection, field rotating medicine is to fresh-keeping and soil disinfections of fruit and vegetable such as the control of multiple kinds of crops diseases such as bacterial leaf streak of rice, bacterial leaf-blight, rice blast, bakanae disease, pythium rot, banded sclerotial blight, wheat rust, root rot, cucumber downy mildew, anthracnose, bottle gourd powdery mildew, hesperidium aurantium, mango, capsicums.This disinfectant is used in agricultural.Have broad spectrum activity, efficient, low toxicity, inexpensive, the characteristics of not having sudden change, no teratogenesis, non-environmental-pollution.
Description
The invention belongs to the method for crop disease control.
In crop disease control, particularly rice paddy seed sterilization, acid mercuric chloride commonly used traditionally, enemy withered two and formalin and other organic mercury agent etc., but these organic mercurials have because of its high residual hazard disabled, what have is big to human toxicity, easily damages seed sprouting power, and preventive effect is undesirable.In recent years adopted both at home and abroad that a collection of new drug such as benzene thiophene are clear, withered two, the riverization 018 of Fujione, DT, the spirit of powder rust, tpn, " shuang xiao ling ", enemy etc., but have the deficiency of sterilization broad spectrum activity difference more, what have also will be with a large amount of foreign exchanges purchases, the preventive effect that has is not ideal enough.
The objective of the invention is to invent a kind of method, only use a kind of compound just can and prevent and treat the main disease of various crops to seed disinfection, and preventive effect is remarkable, cost is lower.
The present invention's TCCA(sym-closene) medicine of curing the disease as sterilization.The molecular formula of TCCA is C
3O
3N
3Cl
3, this medicine has strong antibacterial and sterilization functions for the fungoid of crops or the pathogen of bacterial disease.Studies show that: the fungistatic effect of TCCA100～700 times liquid is better than 0.03% acid mercuric chloride liquid, 50 times of liquid of formalin, 500 times of liquid of carbendazim.Its bactericidal effect is: soaked 16 hours or after 500 times of liquid soak 24 hours, can all kill the pathogen of rice blast, bakanae disease, bacterial leaf-blight, bacterial stripe through 100-300 times of liquid.Handle the effect that seed rice improves germination rate in addition with TCCA, with the seed soaking of TCCA300-500 times of liquid after 12～24 hours, constant indoor temperature is cultivated vernalization can improve germination rate 4-6%, and outdoor production application is generally than using 50 times of liquid seed soaking of formalin or the processing in 3 hours of vexed kind and clear water contrast to improve germination rate 5-8%.To seed rice without abundant dormancy, can effectively break the seed dormancy phase, improve germination rate 14.5%-40%.Control, fruit fresh-keeping, soil disinfection to cotton seed sterilization, wheat rust, root rot, cucumber downy mildew, anthracnose, bottle gourd powdery mildew all have positive effect.Because hypochlorous acid soluble in water exists with molecular state, the speed of its permeates cell membranes is more faster than hypochlorite ion, can make the cell dawn of pathogen suffer that in vain oxidative deformation causes death, so its sterilizing ability is 100 times of hypochlorite ion.Hypochlorous acid solution is decomposed into CO under sunlight, hydrolysis and microbial action
2And NH
3Overflow, thus noresidue, non-environmental-pollution.Teaching and research room carries out toxicity test through Zhongshan Medical College sanitary system labor health and occupational medicine, and assert that TCCA is to people and animals' low toxicity: small white mouse LD50 is 877 a milligrams/kg body weight, and big white mouse LD50 is 750 a milligrams/kg body weight, and this medicine does not have sudden change, no teratogenesis.Therefore TCCA is a kind of comparatively ideal agricultural bactericidal disinfectant.
Through field experiment for many years, prove with TCCA to have wide spectrum, efficient, low toxicity, inexpensive, pollution-free, no teratogenesis, do not have the characteristics of sudden change as the medicine of control corps diseases, use has bright prospects on agricultural.
Below be use embodiment and the effect contrast thereof of the present invention to different diseases:
1. rice seed disinfection: is that 0.2% ratio is dressed seed earlier and afterwards preserved through the TCCA of pulverization process dry powder in accounting for weight ratio, prior to seeding again with TCCA500-300 times of liquid seed soaking 12-36 hour, dry storage after seed dressing or the seed soaking, the germination rate of checking after 30-40 days is higher than and does not deal with contrast, and the medicinal powder seed dressing is handled 144-166 days germination rate comparison according to high 6-12%.Through field efficacy investigation, the preventive effect of bacterial stripe, rice blast, bakanae disease is reached 88-100%.
2. field control: prevent and treat rice disease with TCCA500-800 times of liquid, 500 times of liquid with do not handle contrast, the rotten sick preventive effect of cotton is reached 97-98%, banded sclerotial blight is better than 1200 times of jinggangmycins, bacterial leaf-blight is equivalent to 018 2000 times in riverization, and 500 times of phenazine oxides doubly are better than 900 times of kitazine to rice blast TCCA900,750 times of iprobenfos are received rice and are added 670 times.
3. cotton seed sterilization: handle with TCCA500 times of liquid seed soaking, the three lukewarm water methods of opening a cold that the seedling blight preventive effect is better than using always, and effective, method is easy.
4. 200 times of liquid preventive effects of the control of wheat rust: TCCA500-200 times liquid and powder rust spirit are suitable, are better than fluorine silicon uric acid.
5. cucumber, bottle gourd disease control: spray with TCCA500 times of liquid, a little less than 1500 times of triadimefons, 200 times of " shuang xiao ling "s are better than 600 times of tpns to the powdery mildew preventive effect of cucumber downy mildew, anthracnose, bottle gourd, " Chongqing 8702 " 500 times, and DT etc. contrast agricultural chemicals.
6. with TCCA800-1000 times of liquid processing rape, root rotof flax there is certain preventive effect.
7. handle hesperidium aurantium, mango, capsicum fresh-keeping effect with TCCA400-500 times of liquid and be better than or be equivalent to 800 times of topsins, to fish disease prevention and cure: the TCCA preventive effect is better than bleaching powder, lime.
8. every square metre of area medication of soil disinfection 8-10 gram both can be sterilized, and reduced pythium rot, also can improve percentage establishment of seedling 5-14%.
9. can soak seed with 300-500 times of liquid to the multiple kinds of crops seed disinfection, the field rotating medicine control can be used 300-1000 times of soup and be sprayed.
