Nigeria world cup veteran Efetobore Sodje responded to criticism from Huddersfield Boss Peter Jackson by scoring his first goal for the club as Town won their fifth straight match.
Defender Sodje, 33, headed in Stephen Yates' deflected right-wing cross on 72 minutes after Boston had failed to clear a corner properly.
Sodje's repost came after Jackson suggested in a newspaper article on Friday that he does not get on the scoresheet often enough.
Academy product Anthony Lloyd sealed the points by cheekily nutmegging visiting keeper Paul Bastock after latching on to Jon Stead's throughball 4 minutes from time.
Huddersfield created a stack of chances throughout the game, without ever really hitting top gear.
The most dangerous effort came in a spell late in the first half when Town won seven corners in a row.
Bastock produced a string of fine saves to deny Sodje, Stead and Jonathan Worthington- who all latched onto set pieces whipped in by winger Danny Schofield.
The Pilgrims had few chances at the other end but defended stoutly during Huddersfield's most demanding spells of pressure, until they were finally broken by Sodje's effort.
Veteran Boston midfielder Neil Redfearn, 38, went closest for the visitors, but he was left to rue his bad luck when a terrific 25-yard drive cannoned off the post with barely ten minutes played.
The ball hit the inside of the left hand upright and curled across the face of goal to safety.
Boston continued to work hard throughout the game and striker Stuart Douglas caught the eye with a match long tussle with Sodje.
On one of the rare occasions when Douglas escaped Sodje's clutches early in the second half. The Frontman blasted wide from close range.
The result does nothing to improve the visitors' awful away record - United had won just twice on the road all season and have scored only seven goals in fourteen away games so far - and manager Neil Thompson knows he has his work cut out to turn the situation around.
"The players worked hard and I could not fault them for their performance, but we are just lacking that little bit of quality," Thompson said.
"At times I thought we gave the ball away too cheaply and that is not the sort of thing you should be doing when you come to a place like Huddersfield.
"It is something we are going to have to work on in order to improve our away form."
