Problems solved by technology

With the gradual popularization and popularization of these two fungicides, the problem of resistance has become more and more prominent, especially carbendazim. Since the 1980s and 1990s, carbendazim has become the first choice for farmers to prevent fungal diseases in field crops. Due to Long-term use of this single agent makes most strains show extremely high resistance to carbendazim, and the resulting consequences are unfavorable factors such as increased application amount, increased application frequency, and reduced control effect

Embodiment 4

[0069] Table 4 Example 4 field efficacy test on rape sclerotinia

[0070]

[0071] 4, Utilize the field efficacy test of embodiment 1 (75% water dispersible granule) to control rice panicle blast

[0072] The experiment was conducted in Group 2, Chiqi Village, Xinfeng Town, Dafeng City, Jiangsu Province. This area is an old disease area of ​​rice blast, and has developed resistance to carbendazim and other agents after monitoring. The previous stubble of the experimental field was wheat, and the depth of the spraying water layer was 1 cm. The rice variety was Yandao No. 9. The soil type of the test area is paddy soil, with a pH value of 7.5, a perennial groundwater level of 60cm, flat terrain and good irrigation conditions. Spray once at the initial stage of rice breach, use 30ml, 40ml, 50ml of 75% carbendazim prochloraz copper salt water dispersible granules per mu and spray with water. Changjiang 10 type hand pressure sprayer, the nozzle diameter is 0.7mm.

Abstract

The invention relates to a germicide composition with synergistic interaction, which is characterized in that, the composition is a compound preparation consisting two active components and pesticide conventional assistant; in the composition, active component a is carbendazim, and active component b is prochloraz-copper chloride complex; the weight ratio of component a and component b is 1: (0.05 to 20). The germicide composition can be widely applied to the fungi harm control of rice, wheat, economic crops, fruits, vegetables and other crops. Through the complex formulation of germicides with different mechanisms and action modes, the invention has good effect on fungicide spectrum, enlargement, fungi resistance delay, control effect improvement and other aspects. Testing has proved that the composition of the invention has the advantages of wide fungicide spectrum, low consumption cost, safe use to environment and plants and other excellences.

Description

technical field [0001] The present invention relates to a fungicide composition with synergistic effect, the fungicide composition can be used for the harm of germs on crops such as cereals, rice, fruits, vegetables and economic crops, has protective and therapeutic effects on crops, and exhibits extremely strong antibacterial and bactericidal activity. The invention belongs to the field of agricultural plant protection. technical background [0002] Both carbendazim and prochloraz copper salt are very effective fungicides in agricultural production. Prochloraz copper salt is a kind of metal salt derivative compound of prochloraz. Due to the complexation of copper ions in the prochloraz structure, a new class of fungicides has been formed. The fungicidal activity of this kind of fungicides is higher in prochloraz and copper preparations. The bactericidal mechanism of carbendazim and prochloraz copper salt is completely different. The mechanism of carbendazim is mainly by ...
