## Abstract

The present disclosure provides a method for controlling Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4). The present disclosure mainly aims to solve the problem of effectively inhibiting the Foc TR4, but the existing fungicides cannot effectively inhibit the Foc TR4 without damage to banana plants. By treating with the fungicide disclosed by the present disclosure, the growth of the Foc TR4 can be limited, and there is no adverse effect on banana plants.

## Claims

### Claim 1

A method for controlling Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4), comprising:
preparing an agrochemical agent, wherein the agrochemical agent includes a compound xerucitrinin A.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the agrochemical agent for controlling Foc TR4 further comprises an agricultural-pharmacologically acceptable adjuvant.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the agrochemical agent for controlling Foc TR4 further comprises other agrochemical agents for controlling Foc TR4.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the agrochemical agent for controlling Foc TR4 is in a pharmaceutical dosage form selected from the group consisting of a wettable powder, a water dispersible granule, a suspension and an emulsifiable concentrate.

### Claim 5 (depends on 1)

The method according to claim 1, wherein a concentration of the compound xerucitrinin A in the agrochemical agent for controlling Foc TR4 is 3 mM.
