A. spread to Thailand and Vietnam by 2018 and was now estimated to be present in 10 percent of the surfaces cultivated in the region threatening millions of smallholders that cultivate cassava and generates -- Estimation is being done in present, so "is now estimated" is correct
B. had spread to Thailand and Vietnam by 2018 and is now estimated to be present in 10 percent of the surfaces cultivated in the region, threatening millions of smallholders who cultivate cassava and generate -- CORRECT, "by 2018" indicator makes past participle correct and right usage of participial modifier phrase (threatening...)
C. spreading to Thailand and Vietnam by 2018 and is now estimated to be present in 10 percent of the surfaces cultivated in the region threatening millions of smallholders cultivating cassava and generating -- wrong parallelism
D. had spread to Thailand and Vietnam by 2018 and had been estimated to be present in 10 percent of the surfaces cultivated in the region, threatening millions of smallholders who cultivate cassava and generate -- same reason as A
E. has spread to Thailand and Vietnam by 2018 and is now estimated to be present in 10 percent of the surfaces cultivated in the region, threatening millions of smallholders who cultivate cassava and generates [/color[color=#ff0000]]-- The situation ended in past (2018), so present perfect tense is wrong; also has SVA issue.
So, B

A. spread to Thailand and Vietnam by 2018 and was now estimated to be present in 10 percent of the surfaces cultivated in the region threatening millions of smallholders that cultivate cassava and generates - was now
B. had spread to Thailand and Vietnam by 2018 and is now estimated to be present in 10 percent of the surfaces cultivated in the region, threatening millions of smallholders who cultivate cassava and generate - sequence-> spread ---- by 2018, use of past perfect is correct with this sequencing. Comma threatening correctly modifies the result of the previous clause
C. spreading to Thailand and Vietnam by 2018 and is now estimated to be present in 10 percent of the surfaces cultivated in the region threatening millions of smallholders cultivating cassava and generating- Cassava Mosaic Disease spreading to Thailand and Vietnam by 2018- it is a fragment
D. had spread to Thailand and Vietnam by 2018 and had been estimated to be present in 10 percent of the surfaces cultivated in the region, threatening millions of smallholders who cultivate cassava and generate - use of past perfect continuous tense is wrong. Per the sentence the estimation is done now(in present)
E. has spread to Thailand and Vietnam by 2018 and is now estimated to be present in 10 percent of the surfaces cultivated in the region, threatening millions of smallholders who cultivate cassava and generates-generates should be generate
