Question

What is the maximum rate that can be used to control the prostrate weed infestation in a zoysia grass lawn?

1) 1 kg per acre
2) 2 kg per acre
3) 3 kg per acre
4) 4 kg per acre

Answer 1

Without specific details on the herbicide, it's not possible to define the maximum rate for controlling prostrate weed in zoysia grass lawns. Herbicide use should always follow label instructions to avoid damaging the lawn or the environment.

Step-by-step explanation:

To control prostrate weed infestation in a zoysia grass lawn, it's crucial to use the correct rate of herbicide. The question does not specify which herbicide is being referenced; however, for herbicides like atrazine, usage rates can vary. It is important to follow the label instructions on the herbicide for the specific type of grass and the particular weed in question. Over-application can damage the zoysia grass or the environment, while under-application will not control the weeds effectively.

In general, weed control in agriculture and horticulture can involve several methods, including chemical control with herbicides, biological control using organisms that target weeds, and cultural control methods that alter the environment to reduce weed prevalence. The correct application rate is highly specific and should be determined based on the manufacturer's guidelines, considering factors such as the type of herbicide, the type of grass, and the extent of the weed infestation.

Without specific details on the herbicide being used, it is not possible to provide a definitive answer to the question of the maximum rate for controlling prostrate weed infestations in zoysia grass. It is imperative to consult a professional or the herbicide's label for accurate instructions.

Answer 2

The maximum rate to control prostrate weed infestation in a Zoysia grass lawn is 4 kg per acre. Option 4 is correct.

Step-by-step explanation:

Prostrate weeds, like crabgrass or goosegrass, can be particularly invasive in zoysia grass lawns. To effectively manage this infestation, the maximum rate for control typically involves applying 4 kg of appropriate herbicide per acre. This rate is established based on the resilience of zoysia grass against herbicides and the need to effectively target the prostrate weeds without causing substantial harm to the desirable grass. Using lower rates might not provide adequate suppression of the weeds, while higher rates can risk damaging the zoysia grass. Therefore, the 4 kg per acre rate strikes a balance, effectively combating the prostrate weeds while maintaining the health and integrity of the zoysia grass lawn.

The correct answer is 4) 4 kg per acre.
