B. The greater the BOD of waste water, more is its polluting potential
C. Trichoderma species are effective biocontrol agents of several plant pathogens
D. Baculoviruses are pathogenes that atack several Plant pathogen

Answer

To determine which statement is incorrect, we will analyze each statement provided in the question step by step.

### Step 1: Analyze the first statement
**Statement:** The Green Revolution was dependent to a large extent on the plant breeding technique.

**Analysis:** The Green Revolution, which took place in the 1960s, involved the introduction of high-yielding varieties of crops, particularly wheat and rice. This was largely due to advancements in plant breeding techniques. Norman E. Borlaug, known as the father of the Green Revolution, played a significant role in this development. Therefore, this statement is **correct**.

### Step 2: Analyze the second statement
**Statement:** The greater the BOD of the wastewater, more is the polluting potential.

**Analysis:** BOD, or Biological Oxygen Demand, measures the amount of oxygen that microorganisms will consume while decomposing organic matter in water. A higher BOD indicates a higher level of organic pollution, as more oxygen is required to break down the sewage. Thus, this statement is also **correct**.

### Step 3: Analyze the third statement
**Statement:** Trichoderma species are used as a biocontrol agent of several plant pathogens.

**Analysis:** Trichoderma is a genus of fungi that is widely recognized for its role as a biocontrol agent against various plant pathogens. It helps in promoting plant health and protecting against diseases. Therefore, this statement is **correct**.

### Step 4: Analyze the fourth statement
**Statement:** Baculovirus are the pathogens that attack several plant pathogens.

**Analysis:** Baculoviruses are a group of viruses that primarily infect insects, particularly arthropods, and are not known to attack plant pathogens. They are often used in biological control of insect pests, making this statement **incorrect**.

### Conclusion
Based on the analysis of each statement, the incorrect statement is the fourth one: "Baculovirus are the pathogens that attack several plant pathogens."

### Final Answer
The incorrect statement is: **Baculovirus are the pathogens that attack several plant pathogens.**
