Embodiment 1
[0017] Example 1 Indoor efficacy test of the virus control composition of the present invention
[0018] Tobacco virus disease was used as the test object, and the efficacy of the combination of methiamine and morpholinidine hydrochloride was determined by indoor pot method.
[0019] Test method: refer to the Pesticide Indoor Bioassay Test Guidelines YC / T-1996 of the People's Republic of China. The test crops are tobacco susceptible varieties. After germination, 2 seeds are sown in each pot, and the plants with the same growth are selected for use at the stage of 3 leaves and 1 heart. On the basis of the preliminary test, set 5-7 series of mass concentrations according to the activity of the drug. Spray the medicinal liquid evenly on the leaf surface until it is completely wet, preferably without dripping water, and wait for the medicinal liquid to dry naturally for later use. 10 pots per treatment. And the treatment containing only solvent and surfactant but no active i...

Abstract
The invention relates to a plant disease-controlling composition and disease-controlling pesticides. The composition comprises methyl thiadiazole induced amine and moroxydine hydrochloride according to the weight proportion of 1:50 to 50:1, and preferably, the compositional proportion is 1:30 to 30:1. After being blended, the two components with different mechanisms and patterns of action can produce a remarkable synergistic effect. The composition and acceptable auxiliary components in pesticides can be combined to form a variety of available disease-controlling pesticides in the common agent form, and the composition is suitable for controlling the viral diseases of crops such as tobacco, capsicum, tomato and cucumber, can effectively reduce the dosage of each single agent, helps to broaden the application range for control, delays the generation of the pesticide resistance of plants, prolongs the durability, and has a significant popularization value.
Description
technical field [0001] The invention relates to a plant virus control composition and corresponding virus control pesticides, including but not limited to the virus control composition and corresponding pesticides applicable to the control of viral diseases of tobacco, pepper, tomato, cucumber and other crops. Background technique [0002] Tobacco mosaic virus (TMV) has occurred in various tobacco producing areas in my country, and Heilongjiang, Liaoning, Jilin, Shandong, Henan, Anhui, Sichuan, Guangdong and other provinces have been severely affected. The incidence rate of this disease in the field is generally 5-20%, but the tobacco plants in the adjacent fields often remain strong. Infection at the seedling stage or initial stage of the field, the loss can reach 30-50%, but the infection after budding has no significant effect on the yield. After the diseased leaves are prepared, the color is uneven, the taste is poor, and the quality is reduced. Tobacco common mosaic ...
