| Sulphuric acid is still the most widely used desiccant on potatoes, used to wither the leafy foliage, or haulm, before harvesting. |

| Sulphuric acid is widely used to wither the leafy foliage, or haulm, on potatoes before harvesting. |
|
| Straw or haulm from treated crops must not be used as animal feed for at least 4 days after last application. |
|
| Before harvesting haulm is pulled, cut or killed using chemicals. In general haulm destruction takes place 10-15 days before harvest. |
|
| The standard sieving webs with a large overlapping surface enable a separation of haulm and soil from the potatoes, without loss. |
|
| This means an attached frame, synthetic or diabolo, big haulm intake rollers and an easy depth adjustment. |
|
| Wit hit mesh chain, the machine can be used in an early stage, namely for completely green haulm. |
|
| Apart from AVR machines, we also take care of the parts of all the potato cultivators and haulm toppers of Rumptstad. |
|
| Two haulm rollers combined with a 1.65 m pintle belt guarantee an efficient haulm removal. |
|
| The haulm intake rollers and the second and third sieving web ensure a perfect haulm discharge. |
|
| The Spirit family comes, as standard, with a digging belt and a new combination of haulm, sieve and transport belts. |
|
| The three point linkage on the machine can easily be converted so that the machine can be transformed from a rear to a front haulm topper. |
|
| Due to the large uptake, the synthetic diabolos, large haulm intake rollers and the central depth adjustment, an optimal result can be obtained. |
|
| Long days combined with relatively high temperatures tend to delay tuber initiation and stimulate haulm growth. |
|
| After the haulm has been destroyed, the growers and the NAK keep a close eye on the plots so as to detect regrowth in good time. |
|
| This includes mechanical removal of the haulm, the use of a foliar desiccant and root pruning to prevent any regrowth. |
|
| However, destroying the haulm at the right time will not guarantee that the seed potatoes will comply with the virus standards. |
|
| Therefore, we can supply the whole machine series for potato harvest in these countries. from soil cultivation and seeding, over haulm topping and harvesting to landlevelling. |
|
| Each season, the NAK determines the best times for destroying the haulm. |
|
| For example, it has been shown that woodchip, pea haulm and rape haulm works well for drainage and are good underneath straw. |
|
|
|
| However some advocate earthing up incrementally as the haulm grows but there is little evidence to suggest that one method is better than the other. |
