Medicament for treating rice blast

Abstract

The invention discloses a medicament for treating rice blast. The medicament is prepared from 10 to 20 percent of albendazole, 70 to 75 percent of Chinese herbal medicament extracting solution and 5 to 30 percent of auxiliary agent, wherein the Chinese herbal medicament extracting solution is prepared by mixing Chinese herbal medicinal materials such as indigowoad root, baical skullcap root and weeping forsythia according to a mass ratio of 1:1:1 and then extracting the mixture by using 65 percent alcohol; the auxiliary agent is an emulsifying agent and a thickening agent; the emulsifying agent is 4 to 25 percent based on the total mass of all the materials; the thickening agent is 1 to 5 percent based on the total mass of all the materials; the model number of the emulsifying agent is 2201 or 4203; and the thickening agent is amylin or xanthan gum. The medicament for treating rice blast has the characteristics that: the medicinal effect is good and is better than the indoor biological test effect of the conventional medicament for treating rice blast; the bacteriostatic rate reaches 100 percent; field tests prove that the preventing effect reaches to over 90 percent; medicament resistance is difficult to generate; and the medicament cost is low. The medicament for treating the rice blast is suitable for preventing and treating rice blast.

Description

technical field [0001] The invention relates to the cultivation of plants, in particular, it belongs to the medicine for controlling rice blast in rice. Background technique [0002] Rice blast (Rice blast), also known as rice fever, fire blast, knocking head blast, hanging neck blast, is caused by the infection of rice by the pathogen Pyril sp. macules, and even lesions that curl up and die. In the past, the main agents used to control rice blast were amida, tricyclazole, etc., and the indoor bioassay results showed that the bacteriostatic rate was not high. [0003] After searching, there are many Chinese patent applications related to rice blast control. In recent years, there are No. 200410014349.7 "a compound agent for preventing and treating rice blast", and No. 200610048661.7 "a microbial anti-rice blast agent and its preparation method and application. ", No. 200710186894.8 "A Fungicidal Composition for Controlling Rice Blast", No. 200810051322.3 "New Environmental...
