FRANKFURT, Nov 12 (Reuters) - Bayer on

Tuesday lowered its full-year operating earnings guidance and

took billions in write-downs on agricultural markets in Latin

America, becoming the latest maker of farming supplies to be

burdened further by low demand.

The German group said it now expects to generate earnings

before interest, taxes, depreciation and amortisation (EBITDA),

adjusted for special items and the impact of currency swings, of

between 10.4 billion euros ($11.1 billion) and 10.7 billion

euros, down from a previous forecast of 10.7-11.3 billion euros.

The group's July-to-September EBITDA, adjusted for one-off

items, fell almost 26% to 1.25 billion euros, missing the

average analyst estimate of 1.31 billion euros posted on the

company's website, as the company cited weak agricultural

markets in Latin America.

The agriculture unit of domestic rival

BASF

last month reported a plunge in earnings as

lower prices and weak overseas currencies outweighed higher

volumes.

U.S. agrichemicals competitor

Corteva ( CTVA )

last week reported a larger-than-expected loss,

also hurt by lower prices, leading the company to cut its

full-year sales outlook.

Bayer added that special charges of 4.1 billion euros,

mainly from write-downs on intangible assets in the Crop Science

division, resulted in a quarterly net loss of 4.18 billion

euros, compared with a loss of 4.57 billion euros a year

earlier.

It confirmed its previous currency-adjusted guidance for

2024 sales and earnings per share before certain items.
