Problems solved by technology

However, due to the repeated and unreasonable use of chemical pesticides for a long time, the rice blast fungus has produced varying degrees of resistance to many current chemical control agents, and the emergence of drug resistance will double the number of control times and the amount of pesticides used in production. increase, the cost of prevention and control will also increase accordingly, and the pollution to the environment will be more serious

Embodiment Construction

[0034] The present invention will be described in more detail below in conjunction with the examples, but the embodiments of the present invention are not limited to these examples, and the parts described in the examples are all by weight.

[0035] Embodiment of the present invention: Weigh 10 parts of the original drug of 96% citronellal and 10 parts of the original drug of 98% methylheptanone, add 10 parts of emulsifier Nongru 0202C, 20 parts of OX-7513, and 15 parts of co-solvent to stabilize 0.5 parts of citronellal, supplemented with water, and cut for 1 hour to obtain 20% citronellal·methyl heptanone microemulsion (ME).

[0036] The 20% citronellal methyl heptanone ME obtained above was used to control rice blast field efficacy test, and the test results are summarized as follows:

[0037] In August 2014, in the rice test field of Jiuzhou Town, Huangping County, Guizhou Province, rice blast has occurred in this area over the years. The rice variety in the test site is K...

Abstract

The invention discloses a synergism composition of phytochemicals controlling rice blast. The synergism composition of phytochemicals controlling the rice blast is made of citronellal and methyl heptanone. According to the synergism composition of phytochemicals controlling the rice blast, the citronellal and the methyl heptanone are compounded and mixedly applied, obvious synergism function are achieved on inhibition of mycelial growth and spore germination of the rice blast, the control efficiency can be up to about 70%, the controlling effect is obvious, dosage of pesticide can be lowered effectively, the labor intensity is decreased, the cost is saved, and the problem of pesticide abuse is solved. The synergism composition of phytochemicals controlling the rice blast is simple, particle, wide in material source, low in cost and good in using effect.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a synergistic composition of botanical compounds for preventing and treating rice blast. Background technique [0002] Rice is one of the important food crops in my country. Every year, rice blast causes serious economic losses to rice production. In some rice planting areas, due to the large area of ​​rice blast, the disease is serious, and sometimes it is almost impossible to harvest. Rice farmers have suffered enormous economic losses. At present, in production practice, single or compound chemical pesticides are generally used for the control of rice blast. However, due to the repeated and unreasonable use of chemical pesticides for a long time, the rice blast fungus has produced varying degrees of resistance to many current chemical control agents, and the emergence of drug resistance will double the number of control times and the amount of pesticides used...
