Abstract
The present invention discloses Caijunke-pesticide for preventing and controlling diseases of crops, which is composed of effective components of procymidone and Sanmate in the weight ratio of 1: 0.5 to 30. The present invention has the advantages of high efficiency of prevention, few medication number of times, low cost, high safety, low toxicity and broad sterilization spectrum; besides the present invention can be used for preventing and controlling sclerotinia rot of colza for the rape production, the present invention can also be used for preventing and controlling the gray mold and the sclerotinia of vegetables for the production of the vegetables, and can be used for crops, such as fruit trees, tea trees, tobacco, etc.
Description
Technical field:
The present invention relates to a kind of agricultural chemicals that is used for preventing and treating in the agricultural production disease.
Background technology:
The medicament of present known control sclerotinia rot of colza has red mould clear, carbendazim etc., owing to use year after year, has produced resistant strain, and preventive effect descends year by year.Though chemical control such as iprodione, dimethachlon sclerotinia rot of colza effect is better, cost is higher, and the peasant is difficult to accept.
Summary of the invention:
The object of the present invention is to provide a kind of Caijunke agricultural chemicals that can effectively prevent and treat crop pests such as sclerotinia rot of colza.
Technical solution of the present invention is:
A kind of Caijunke agricultural chemicals of preventing and treating corps diseases, its feature: effective ingredient is procymidone and carbendazim, and both weight ratios are: procymidone: carbendazim=1: 0.5～30.
The weight ratio of procymidone and carbendazim is 1: 1.5～3.The weight ratio of procymidone and carbendazim is 1: 1.67.Described Caijunke agricultural chemicals is that employing dispersing agent NNO or detergent LS are auxiliary agent, and adopting precipitated calcium carbonate is the wetting powder that filler is made.
Above-mentioned procymidone has another name called Sukeling, SP 751011.
The invention has the beneficial effects as follows: the one, the preventive effect height, the preventive effect of 50% wetting powder, 80 gram/mus of the present invention is 83.15%, is higher than single with the preventive effect 72.4% of 50% procymidone, 50 gram/mus and the preventive effect 60.8% of 25% carbendazim, 200 gram/mus.Co-toxicity coefficient (CTC) to Sclerotinia sclerotiorum is 233.17, and greater than 200, synergy is remarkable; The 2nd, reduce the medication number of times, save cost.Caijunke medication preventive effect once is equivalent to the preventive effect of carbendazim secondary, has improved labor productivity; The 3rd, safety, result of the test, 50% Caijunke, 60～120g prevents and treats sclerotinia rot of colza, does not see any symptom of chemical damage, to growth of rape safety; The 4th, low toxicity, rat acute per os LD50 value is greater than the 5000mg/Kg body weight, acute through skin LD50 value greater than leather 000mg/Kg body weight, be suitable for nuisanceless crop production; The 5th, fungicidal spectrum is wide, removes to be used for preventing and treating sclerotinia rot of colza in the rape production, also can be used for vegetables and produces upward control eliminating vegetable botrytis, vegetables stalk break, also can be used on the crops such as fruit tree, tea tree, tobacco.
Indoor antibacterial test result: (table 1)
The different proportionings of procymidone, carbendazim are to the growth inhibition value of Sclerotinia sclerotiorum
| Medicine proportionings at different levels | Stalk break bacteria growing value (mm) (5 repetitions) | On average | Growth inhibition percentage (%) |
| Procymidone 5g: carbendazim 35g | 5，4，7，5，5，4 | 4.8 | 76％ |
| Procymidone 10g: carbendazim 30g | 3，3，3，3，3 | 2.8 | 86％ |
| Procymidone 15g: carbendazim 25g | 2，2，3，2，2 | 2.2 | 89％ |
| Procymidone 20g: carbendazim 20g | 4，4，4，3，4 | 3.8 | 81* |

| Procymidone | 7，6，7，7，7 | 6.8 | 66％ |
| Contrast (CK) | 20，17，22，22，19 | 20 |
Result of the test shows procymidone and carbendazim is composite that Sclerotinia sclerotiorum is had good inhibitory effect, and in 5 prescriptions, with procymidone 15g: it is the highest that the proportioning of carbendazim 25g suppresses percentage, reaches 89%; Single agent is starkly lower than complex preparation to the inhibition percentage of germ.
The different proportionings of 50% procymidone carbendazim are to the preventive effect of sclerotinia rot of colza;
The result of the test of field control sclerotinia rot of colza: (table 2)
| Medicament and proportioning | Diseased plant rate (%) | x | Disease index | x | Disease refers to preventive effect % |
| A (procymidone 10g: carbendazim 30g) | 3.0，3.8，2.6 | 3.13 | 2.11，2.71，2.90 | 2.57 | 87.55 |
| B (procymidone 15g: carbendazim 25g | 3.4，2.3，2.4 | 2.7 | 0.88，1.03，1.35 | 1.09 | 94.74 |
| C (procymidone 20g: carbendazim 20g | 4.1，3.9，3.4 | 3.8 | 3.07，3.99，3.18 | 3.41 | 83.50 |
| D (carbendazim 35g) | 10，3，12，1，9，3 | 10.57 | 8.13，7.89，7.43 | 7.82 | 62.18 |
| E (procymidone 25g) | 8.3，6.9，7.4 | 7.53 | 6.65，7.48.6.03 | 6.72 | 67.49 |
| Contrast | 38.4，47.0，41.8 | 42.4 | 23.1，20.4，18.5 | 20.67 |
Result of the test shows: mixture is better than each single agent to the preventive effect of sclerotinia rot of colza; Procymidone 15g wherein: the proportioning of carbendazim 25g is best proportioning.
